* improvements to caching for lists and relationship to accounts / follows * fix nil panic in AddToList() * ensure list related caches are correctly invalidated * ensure returned ID lists are ordered correctly * bump go-structr to v0.8.9 (returns early if zero uncached keys to be loaded) * remove zero checks in uncached key load functions (go-structr now handles this) * fix issues after rebase on upstream/main * update the expected return order of CSV exports (since list entries are now down by entry creation date) * rename some funcs, allow deleting list entries for multiple follow IDs at a time, fix up more tests * use returning statements on delete to get cache invalidation info * fixes to recent database delete changes * fix broken list entries delete sql * remove unused db function * update remainder of delete functions to behave in similar way, some other small tweaks * fix delete user sql, allow returning on err no entries * uncomment + fix list database tests * update remaining list tests * update envparsing test * add comments to each specific key being invalidated * add more cache invalidation explanatory comments * whoops; actually delete poll votes from database in the DeletePollByID() func * remove added but-commented-out field * improved comment regarding paging being disabled * make cache invalidation comments match what's actually happening * fix up delete query comments to match what is happening * rename function to read a bit better * don't use ErrNoEntries on delete when not needed (it's only needed for a RETURNING call) * update function name in test * move list exclusivity check to AFTER eligibility check. use log.Panic() instead of panic() * use the poll_id column in poll_votes for selecting votes in poll ID * fix function name
