This cleans up all of the usage of `<a>` in the codebase. Now all
external links get the appropriate attributes added.

This significantly speeds up `yarn lint` for me. It also ensures we’re
listing all source files in the project, including the `.eslintrc` files
and any other files that may be present.

This fixes an error that you’ll see about an unused export if you build
before linting.

This will reduce install/lockfile size but won’t affect the built bundle
size. Still nice, hopefully!

I checked through the other references to `navigate` and none of them
appeared to be affected.

Another monkeypatch bites the dust.

AFAIK there is no regression in functionality. But please test
yourselves too to double check.

It me it seems the monkey patch is no longer necessary.. At least I'm
not able to reproduce any `escape` key related issues. But LMK what you
think.

The `@reach/listbox` component is used for the custom select component
(for example: for filters).

Just removing some unused/unnecessary scripts and `IS_BETA` env variable
+ the associated code (we don't use this in the OS version of Actual).

Based on Tom's comment
(https://github.com/actualbudget/actual/pull/1058#issuecomment-1568030881

)
I've eliminated all direct use of date-fns and only use the functions in
months.ts.

I've updated the return values in `sync/index` to sensible values based
on how they're being called.

I've updated the type of `msg.value` to be `string | number | null` to
match the values expected by `serializeValue`

Also remove the need to unmount & remount when switching between
accounts. Fixes #1169

For #1152

- New linter rules are now added
- Perhaps the `createPayee` method i've tagged with a disable should be
deleted.
- I have ignored unused methods in Plaid/Mobile as this stuff is still
WIP/experimental?

* Provide `match` prop to class components that still rely on it.
* Fixes #1169
* Fixes an unrelated crash on Payees

Looks like this got missed in the last PR!

Last one before I add the actual linter rules!

None of this code is relevant to people who have used the open source
app. I initially wanted to leave it in so it could be used for major new
features in the future, but as it falls further and further out of date
I think it’s best to just delete it in a clean PR that can be referenced
later if desired.

Following on from #1146 this PR removes all unused exports from
`loot-core/`

Closes #1069

I've not actually tested this change. Which is why I'm not changing it
to direct links (as they might not work).

Instead I'm just applying a very quick patch so the message would not be
misleading anymore.

It now always shows a menu, so the user doesn’t unexpectedly perform an
action.

This PR is for the first item listed in #559: `Expand All / Collapse All
Categories`

For the expand / collapse all categories functionality, I was choosing
between having a single `Expand / collapse all categories` button or one
for each: `Expand all categories` and `Collapse all categories` buttons.

For the initial implementation, I have opted with the latter. Please let
me know which one is the right way to go or if there are other
suggestions and I'll just accordingly.

actual-server does not need to import the full actual-app/api package.
It can import only the CRDT stuff.. so I'm extracting it into a new
package to reduce the size of actual-server and make the link between
things more transparent.

Continuing on from #1139 this PR deletes all function that are not used
anywhere.

The next PR will include all the entire files that are unused & deleted.

This reverts #1029. As raised in #1097, the formatting chosen doesn’t
work well when doing math. There may be a way to balance compatibility
with multiple format styles with handling non-currency amounts
correctly, but it will require some more careful consideration. Re-opens
#894.

URLs with the trailing slash don’t work well — requests end up being
made to `https://example.com//sync/sync`

 and such which can 404

As discussed in #1126 creating separate PRs.

The linter rule isn't actually part of this first PR and will likely be
in the final PR as otherwise it will just fail because all the issues
aren't resolved.

The code is 'ready' though so as soon as this is merged I will open next
one(s)
