fix(podcasts): wire podcast kinds into every consumer; close audit findings

Addresses 10 audit findings from the post-build review:

CRITICAL — non-functional without this:
- LocalCache.justConsume had no branches for kind 54 / 10054 / 10064 / 10154,
  so every podcast event fell through to "Event Not Supported" and was
  silently dropped. Added the four explicit branches (regular event for
  PodcastEpisode; replaceable for the other three).

HIGH — silent invisibility / broken tap-through:
- Home, profile (newthreads + mutual), hashtag, geohash, follow-pack, and
  notification feed filters didn't recognize PodcastEpisodeEvent /
  PodcastMetadataEvent. Episodes were invisible everywhere outside the
  dedicated tab; reactions/zaps on episodes were dropped from the
  notifications feed.
- ThreadFeedView's renderer dispatch had no podcast branch, so tapping a
  feed card opened a plain text-note view. Added explicit cases that call
  the new RenderPodcastEpisode / RenderPodcastMetadata composables.
- The hashtag / geohash / relay / search REQ kind lists didn't include
  podcast kinds, so discovery surfaces returned nothing for them.
- RelayInformationScreen kind→label map gained podcast entries +
  4 new string resources (Podcast Episode, Podcast Show, Authored
  Podcasts, Favorite Podcasts).
- HomeNewThreadFeedFilter.ADDRESSABLE_KINDS gained PodcastMetadataEvent so
  shows surface alongside music/wiki/long-form on the home feed.

HIGH — privacy leak in Quartz:
- FavoritePodcastsListEvent.add(isPrivate=true) was passing
  earlierVersion.tags through untouched, so toggling a previously-public
  favorite to private left the public p-tag intact. Made both branches
  symmetric: each removes the entry from the other half before adding to
  its own. Two regression tests cover the round-trip.

MEDIUM — data hygiene:
- AuthorTag.parse used to accept ANY non-empty slot-2 string as a role
  (rendering a stray relay-hint URL as "Role: wss://relay…"). Now
  validates against the spec-defined {host, cohost, editor} allowlist;
  unknown values resolve to role=null, preserving the pubkey association.

PERF:
- PodcastEpisode renderer was allocating a fresh 96-element WaveformData
  and rebuilding the cover Modifier chain per visible card. Hoisted both
  to top-level constants (FLAT_WAVEFORM, COVER_IMAGE_MODIFIER,
  PLAYER_BORDER_MODIFIER) so the whole feed shares one instance.

CODE QUALITY:
- Extracted PodcastCoverCard as a shared composable used by both renderers
  (was duplicated byte-identical across PodcastEpisode + PodcastMetadata).
- Extracted PodcastFeedLoaded so the Episodes screen and Shows screen
  share one feed body (was duplicated byte-identical).
- Dropped the misleading `group = listOf(singleAssembler)` wrapper in the
  two FilterAssembler files.
- Replaced `mapNotNull { … }.flatten()` with `flatMap { … }` in the
  Communities sub-assembly (the lambda never returns null).

DOCUMENTED:
- PODCAST_KINDS "Following" resolution still goes through kind:3 follows,
  but per NIP-F4 podcasts use their own keypairs tracked via kind:10054.
  Added an inline comment naming the deferred work — proper fix needs
  Account-level 10054 integration which is a separate scope.
