[feature] Filters v1 (#2594)

* Implement client-side v1 filters

* Exclude linter false positives

* Update test/envparsing.sh

* Fix minor Swagger, style, and Bun usage issues

* Regenerate Swagger

* De-generify filter keywords

* Remove updating filter statuses

This is an operation that the Mastodon v2 filter API doesn't actually have, because filter statuses, unlike keywords, don't have options: the only info they contain is the status ID to be filtered.

* Add a test for filter statuses specifically

* De-generify filter statuses

* Inline FilterEntry

* Use vertical style for Bun operations consistently

* Add comment on Filter DB interface

* Remove GoLand linter control comments

Our existing linters should catch these, or they don't matter very much

* Reduce memory ratio for filters
