feat(podcasts): smart episode collections — ALL/ANY match modes + episode rule fields (item 2.4)

The daily briefing needs AND: today's rules engine was OR-only. The
match semantics become a per-collection column
(collections.rule_match_mode, 'any' legacy default | 'all'), flipped on
its own endpoint (PUT /api/collections/:id/match-mode, owner-only —
nothing else on the row changes) and surfaced in the rules page as an
ANY/ALL toggle with matching copy.

Episode rule fields join the vocabulary (plan item 2.4): feed (the
multi-select rides the new `in` operator — comma-separated feed ids),
played (the canonical finished predicate — viewer progress ≥ 0.999,
same as hide_finished), downloaded, published_within (N days), plus
title/description contains. The rules candidate query now carries the
viewer's progress (LEFT JOIN reading_progress) so played/unplayed is
per-user, and TestRules/preview speak the SAME evaluator: the handler's
duplicated field switch is deleted and delegates to
CollectionService.FieldMatches — one vocabulary, one semantics.

Legitimate semantics note: in ANY mode `played:false` matches unplayed
BOOKS too (everything with no progress row) — correct per-rule
behavior, and exactly why the briefing mode exists.

Backward compatibility: every legacy row defaults to 'any' (the old
OR), UpdateCollection keeps the stored mode when the form doesn't send
one, and the evaluator treats absent data honestly (no date → no
match; no progress → unplayed).

Pinned by TestPodcastSmartCollections: the AND-mode briefing
(feed∈{A} ∧ unplayed ∧ <7d = exactly the new episode), OR-mode
widening, owner-only flips, the preview honoring the mode, and
downloaded/contains rules. Also fixes a latent bug the new query
surfaced: UpdateCollectionViewSettings referenced a nonexistent
updated_at column (never exercised until now — the new sibling query
was written without it).
