* Add split creation UI to rule creation modal

* Support applying splits when rules execute

* fix: deserialize transaction before running rules

According to how rules are run in other places in the app, we should be
supplying a "deserialized" (i.e., integer-for-amount and ISO date)
transaction rather than a "serialized" (amount-plus-formatted-date) one.
This fixes a crash in how split transactions are applied, as well as
date-based rules not applying correctly previously (any rule with a date
condition would never match on mobile).

* Add release notes

* Fix missing types pulled in from master

* PR feedback: use `getActions`

* PR feedback: use `flatMap`

* Fix action deletion

* Don't flicker upon split deletion

* Let users specify parent transaction actions (e.g. linking schedules)

* Support empty splits

* Revert adding `no-op` action type

* Support splits by percent

* Fix types

* Fix crash on transactions page when posting a transaction

The crash would probably have occurred in other places too with
auto-posting schedules :/

* Fix a bug where schedules wouldn't be marked as completed

This was because the query that we previously used didn't select parent
transactions, so no transaction was marked as being scheduled (since
only parent transactions have schedule IDs).

* Add feature flag

* Limit set actions within splits to fewer fields

* Fix merge conflict

* Don't run split rules if feature is disabled

* Fix percent-based splits not applying

* Fix crash when editing parent transaction amount

* Auto-format

* Attempt to fix failing tests

* More test/bug fixes

* Add an extra split at the end if there is a remaining amount

* Make sure split has correct values for dynamic remainder

* Remove extraneous console.log

* Another round of prefer-const rule updates

* Release notes

* Fix test error

* Fix sync.ts

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

Fixes #615. I would appreciate double-checking that I didn’t
accidentally delete anything that is important.

Since I’m removing the related API methods, this is technically a
breaking change (even if people would have no reason to remove this
stuff), so we should probably do a major release of the API package.

Another batch of `loot-core` migrated.

* Sort transactions by date in updateCategoryRules

* Update better-sqlite3 to 7.5.0

* Update better-sqlite3 to v8

*  (prettier) adding trailing commas

* More commas

*   upgrade eslint-plugin-import and fix issues

* Change import ordering

* style: enforce sorting of imports

* style: alphabetize imports

* style: merge duplicated imports
