The 'Oldest first' order sorts by PUB DATE, which breaks on Scribl's
migrated podiobooks feeds (messy/all-equal dates). New order value
'reverse' = feed position DESC with a date-DESC tiebreak — dates are
not involved, so nothing can break.
- services.OrderEpisodes: THE single order source of truth (§0 items
3+5a). The four surfaces (sequence JSON, reader chain context, SSR
page list) previously carried three near-identical handwritten
comparators — all now route through one generic helper. The SSR page
list gains a SortDate key (lexical 2006-01-02) so the pub-date
tiebreak is actually chronological; the old comparator compared
'Jan 2, 2006' display strings alphabetically (latent drift bug).
- Dropdown becomes four options: Feed order / Feed order (reversed) /
Oldest first (pub date) / Newest first (pub date).
- Serial suggestion button renamed 'Reverse feed order' (sets reverse,
not oldest) and its response out-of-band-swaps the order select
(PodcastOrderSelectOOB — same mechanism as Download All's policy
select), so the dropdown mirrors the server state immediately.
- Validation: oneof=native reverse oldest newest everywhere.
- Tests: reverse binds via the form wire; messy-dates sequence
returns 3,2,1; existing reorder-safety stays green.
