feat(homepage): Audiobookshelf's own mark, and the voice endpoint in the model block

Audiobookshelf carried the improvised "AB" hex monogram — the fallback for
apps with no icon. Simple Icons carries its brand mark, so the card now
uses /img/apps/audiobookshelf.svg the way Plex and Jellyfin use theirs; the
monogram went to .AGENTTRASH.

frank-tts (Qwen3-TTS 1.7 B base talker on the gfx1151 iGPU) was an
admin-only status tile, so the household read about five cloned voices in
/docs and saw no sign of the door that speaks them. It is now a Model
Information card on the user page beside the three chat models, carrying
the ask-Frank permission note and a privacy note about cloned voices.

miCard grew the shape that requires: art falls back to the card's own `art`
when a card has no StarCraft `unit`, the accent falls back to `.mi-tool`,
and a `tagline` with no `sfx` renders as text instead of a play button that
plays nothing. No audio asset ships with the card on purpose: every pack on
that endpoint is a replica of a real person's voice, so a sample clip would
put a synthetic person's voice in the repo and on the page.

Seams: the model-card contract splits unit cards (equivalence, supervision,
playable voice line) from tool cards (permission note), and the voice
stack's homepage seam now pins category=user with the reason.
