[feature] add support for receiving federated status edits

[NyaaaWhatsUpDoc]

Description

Adds support for GoToSocial properly handling federated status edits. When we receive a status update activity we now correctly store the current state as a historical edit in a new database table, and update the state to the newly received edit. This also handles the case of re-fetching a status we haven't received an update for, but then notice a change in.

Some other changes of note:

• adds getBunColumnDef() migration utliity function which generates the database column definition that bun would normally generate for a given struct field, which greatly simplifies manually adding new columns not having to write the type manually
• drops the unused mentions.updated_at database column
• drops the unused media_attachments.updated_at database column
• adds compile-time type checking of a bunch of our AP interface-able types
• removes the error signature from id.NewULIDFromTime() as we handle the end result in exactly the same manner all over the codebase
• tweaks federated status updates to now only update the necessary columns, possibly now a little cheaper computationally

Big juicy PR! Gonna review it now.

Is it possible to also edit image alt text and have that appear as an update? I'm not sure how it works exactly.

[NyaaaWhatsUpDoc]

we already handle that, though currently in the fetchStatusAttachments() function so tbh i might do some fiddling and also see if mastodon handles media description changes as historic status edits
