Fix dashboard failing to load episodes after RSS import

The root cause was that modernc.org/sqlite stores time.Time as strings
but cannot scan strings back into time.Time, causing ListEpisodes to
fail. Changed PublishedAt and CreatedAt in store structs from time.Time
to string, with format/parse handled at the application level.

Also fixed a secondary issue where the published_at format stored during
import had a duplicated timezone offset.
