This is the last PR with lots of renaming for `loot-core`!

Another batch of `loot-core` migrated.

Hi there, `Peg.js` is unmaintained, so I figure you all would appreciate
if I replaced it with the drop-in replacement of Peggy. This is work I
am breaking out of #918.

Peggy adds new features like source map support that we could use,
although I do not include that in this change-set. It may be useful for
debugging changes to the .pegjs file we have.e

Hi there, 

I try to tackle #798 here. It was suggested to throw this behind a
feature flag, so here it is!

this does its best to import the problem file in #767. 

I am working on this because it would make my work on #918 easier :)

Feel free to set the feature flag to true and try the new importer. The
date parser is not as sophisticated as the one in `node-libofx`, but I
tried 3 different OFX files, one from my bank, one from the mocks, and
one from #767. They all seem to work well enough on that front, but this
is definitely the weak point of the new implementation.

Let me know what you think!

This is an initial concept for adding percent based goal targets.

This version works by using a string in the form of: 
#template 10% of Income <- Income is an income category name. Only
income category names will work here currently.
or
#template 10% of all income<- 'all income' is a keyword in this context
and will base the calculation on the total income for the month.

Some of the nicer touches like Jed's polite notification that the syntax
isn't correct is not implemented here yet.

I've changed the method of calculating the budgeted amount. There may be
a more efficient way of writing the loop, so I'm looking forward to the
review.

This change implements the mathematics of
(Target1+Target2+TargetN-Last_months_category_balance) / (MonthsRemaing1
+ MonthsRemaining2 + MonthsRemaingN) * N. This is an averaged approach
for multiple templates in the same category. It will appear to
overbudget or underbudget some months compared to multiple single
targets in different categories, yet there should always be enough saved
in the category to satisfy the target due.

Setting a target, it's assumed that money will be spent in the
appropriate month, When a target reaches maturity, the money in the
category associated with that target should be spent or moved so the
remaining targets continue to be funded. I don't see an easy way of
fixing that, but I hope this change will be of some help.

Current method:
Notice how the Bills (flexible) category reduces each month, resulting
in larger budgeted amounts later in the goal cycle.

Proposed method:
**Note: The fact that the initial fill in this example equals the
expected fill is a coincidence based on the template values I chose. The
initial fills can be different from expected fill.

Fixes #913. (And probably a few other similar bugs)

This improves the error reporting when issues are found with Goal
Templates. Before these changes, the only error that would be reported
is the "Bills" error in the image while the other issues would be
ignored and not funded.

It turns out this command is not installed by default on macOS.
Fortunately the code doesn’t really require it to be used.

Another batch of files from `loot-core` migrated to TS (loose mode)

Resolves issue https://github.com/actualbudget/actual/issues/888

This PR converts everything (aside from electron) from CommonJS to ESM.
It is needed to reduce the changes that will happen during the migration
to Typescript (as TS does not play nice with CJS).

Basically:
- rewrite `require()` to `import`
- rewrite `module.exports` to `exports`
- introduce `ts-node` to run importers so we can convert them to TS too

Lastly, sorry for this larg-ish PR, not my preference but when I tried
to reduce its scope, I would end up with mixed commons/esm that was even
more tricky to handle.

These files will be automatically recreated by `yarn build:api`,
`yarn build:browser`, and `yarn start:browser`, so we don’t need
them in the repo.

Fixes #840 by creating application-defined SQL functions
(https://www.sqlite.org/appfunc.html) for Unicode-aware implementations
of `LOWER()` and `UPPER()`. This uses
`String.prototype.toLower/UpperCase()` JS method.

I initially wanted to just redefine `LOWER()` and `UPPER()` but due to
[sql.js not supporting the definition of deterministic
functions](https://github.com/sql-js/sql.js/issues/551), I had to just
define them as separate functions and use that in the appropriate
places. It's probably better like that anyway...

I believe this change allows for having multiple 'by' rules in the same
category. It seems to be working well for my purposes, but I would
appreciate further testing to assure there aren't regressions.

Example:

#template 300 by 2023-06
#template 3000 by 2023-08

Before this PR, having these two lines in the notes would only budget
funds for the earliest of the two strings and ignore the 3000 funding
target. With this PR, the sum of the two funding targets will be
respected.

Closes #764

Dismiss the update notification only after clicking "close" button

Previously, we were using an alpha version of date-fns v2. Now we’re
using the latest stable v2.

Part 1 of the conversion. Mostly renaming js to ts and making sure
things make still sense. Added also handy TS ESLint rules.

In order to support the various .web/.electron/... I ended up adopting
`index.d.ts` as pattern to share type definition. Let me know if that
makes sense for you too. Right now the function type definition is
duplicated, but the solution will be importing from `index.d.ts` and
using `const fn: FnDef = () => ...` that way we can keep all variants in
sync from a single type file.

Such rewrite however is better done in another PR otherwise we risk
confusing git and loosing history (rename + too many changes). Another
thing that might do in the next PR is convert all files to ESModules, as
things get confusing between CJS exports, ESM default/named and TS adds
extra complains.

Added onboarding and budget e2e tests. Also fixed an issue for
first-time flows using imports: currently people end up with a blank
white screen after importing. Instead they should see the budget table.

- When parsing an amount string, consider surrounding parentheses to
mean the amount is negative.
- Ensures all input to `parseFloat()` is sanitized.

Closes: #807 

Seems to build fine, will test later.

I'm not sure if this is something you want but it was a simple change so
I figured I might as well contribute it. This PR allows the user to
upload `.blob` files that they may have gotten from server's
`user-files/` folder. This can be useful if the user didn't export the
file but has server backups.

Depends on server change:
https://github.com/actualbudget/actual-server/pull/168

- Add a “hide decimal places” setting to visually hide the `.xx` from
currency values globally
- When hiding the fractional digits, slightly decrease character spacing
to allow more digits to show up

Ref: #327

I noticed that the first run flow is suboptimal for people who want to
import an existing file from Actual/YNAB. I’ve moved the welcome modal
into the management app and set it up to appear when there are no
budgets available (which also has the benefit of allowing people to see
the modal again!)

I think there’s some weirdness around getting the modal to reappear when
deleting a budget file which I want to work out before merging this.

This PR also reorganizes the management app a bit to reduce usage of
modals (currently, hitting escape while the budget list is open leaves
you with a blank page).

- [x] Ensure modal consistently appears when needed (no longer a modal!)
- [x] Fix e2e tests

Upgraded `fast-check` to improve unit test performance.

This is not a full fix for the flakiness. One of the test cases will
still be flaky. But at least this fixes the other test cases thus
improving stability.

Removing
- Debugger
- `perf-deeets`
- `codemirror`

Thanks @kidglove57 for spotting this issue and helping me track down the
cause!
