feat(idaa): add PersistedState store for idaa_loc (not yet wired in)

Creates ae_idaa_stores__idaa_loc.svelte.ts — the Svelte 5 PersistedState
replacement for the idaa_loc persisted() store in ae_idaa_stores.ts.

Mirrors the exact shape of idaa_local_data_struct with full TypeScript
interfaces (IdaaArchivesLoc, IdaaBbLoc, IdaaRecoveryMeetingsLoc,
IdaaLocState). Drops __version, name, and title (not runtime state).

Same localStorage key (ae_idaa_loc) — existing data loads cleanly.
Not wired into consumers yet; pending review before migration.

+// their storage. This is the same trade-off as the events sub-stores.
