Rank shows by what is still waiting, and seed the trailer filters

Two of Peter's asks.

Ordering. A show ranked by its newest unplayed episode, so queueing something
left the show sitting at the top with nothing actually waiting -- his words,
once they're on the queue they're noise in the list. Queued episodes are now
excluded from the ranking for the same reason played ones already were: they
have been dealt with.

That is one clause of SQL, and the fake DAOs return insertion order, so it is
exactly the kind of rule that cannot be pinned off-device. LibraryOrderTest
runs against a real in-memory Room database and covers the change, an older
unqueued episode still counting, played episodes still not counting, and a show
with nothing waiting sorting last rather than vanishing. Confirmed it fails
without the fix before keeping it.

Filters. Peter chose the existing rule engine over anything new, with the rules
set up for him -- and rules live in the database on the phone, so a migration is
the only way to put them there. MIGRATION_4_5 seeds "trailer" and "preview",
both mark-played, as ordinary rules: they show up in the Rules screen and can be
edited, disabled or deleted. Appended after whatever is already there rather
than taking position 0, so they cannot pre-empt rules already relied on, and
INSERT OR IGNORE on a fixed id means deleting one does not bring it back on the
next upgrade. They act only on newly discovered episodes, so nothing already in
the library changes.

One judgement call worth flagging: "preview" will catch a sports show's
legitimate Season preview. It is two taps to delete if it bites.

Schema 4 -> 5, no shape change -- the migration only inserts rows. Covered by
two instrumented tests: seeding after an existing rule, and a 1 -> 5 chain
landing exactly two.

No permission changes. 403 unit tests green, 10 instrumented, detekt and lint
clean. Coverage 65.20 -> 64.90, exception recorded: the new code is a migration
tested on a device, and the coverage report counts unit tests only.
