- removes unnecessary fields / columns (created_at, updated_at)
- replaces filter.context_* columns with singular filter.contexts bit field which should save both struct memory and database space
- replaces filter.action string with integer enum type which should save both struct memory and database space
- adds links from filter to filter_* tables with Filter{}.KeywordIDs and Filter{}.StatusIDs fields (this also means we now have those ID slices cached, which reduces some lookups)
- removes account_id fields from filter_* tables, since there's a more direct connection between filter and filter_* tables, and filter.account_id already exists
- refactors a bunch of the filter processor logic to save on code repetition, factor in the above changes, fix a few bugs with missed error returns and bring it more in-line with some of our newer code

A note on when we should set data structures linked to objects in the database to use the
bun nullzero tag -- this should only be done if the member type is a pointer, or if the
this primitive type is literally invalid with an empty value (e.g. media IDs which when
empty signifies a null database value, compared to say an account note which when empty
could mean either an empty note OR null database value).
Obviously it is a little more complex than this in practice, but keep it in mind!
