feat(lyrics): YouLyPlus karaoke + fix(macos): suppress mic prompt

Two independent user-facing fixes rolled together.

── Lyrics: YouLyPlus provider (issue #172) ──
Adds word-by-word synced (karaoke) lyrics as an alternative lyrics mode.
Backed by the public lyricsplus aggregator (Apple Music / Spotify /
Musixmatch / QQ Music) — no API keys on our side, subscription costs are
borne by the backend operator. Five mirrors are tried on network failure.

Settings → Lyrics now exposes a mode radio (Standard vs YouLyPlus) plus
a static-only toggle. YouLyPlus misses silently fall back to the existing
server + LRCLIB + Netease pipeline so obscure tracks still resolve. The
drag-to-reorder source list is hidden in YouLyPlus mode since the
external aggregator manages its own source priority.

Rendering: per-word spans on each line, active word highlighted with
accent-tinted glow. Subscribed imperatively via usePlayerStore.subscribe
so 500 ms progress ticks do not re-render the whole lyrics block. The
Fullscreen Player reuses the same pattern; the 5-line rail layout is
unchanged. white-space: pre on .fs-lyric-word preserves the trailing
spaces the API embeds in each syllabus token (flex context would
otherwise collapse them).

i18n: new keys in all 8 locales (de, en, fr, nl, nb, ru, es, zh).

── macOS mic-prompt suppression ──
Ships a vendored cpal 0.15.3 at patches/cpal-0.15.3/ wired via
[patch.crates-io]. The only change is in src/host/coreaudio/macos/mod.rs:
audio_unit_from_device now unconditionally uses IOType::DefaultOutput for
output streams instead of conditionally choosing HalOutput.

AUHAL (HalOutput) is classified as input-capable by macOS TCC and
triggers the microphone-permission dialog at first launch / after each
update even for playback-only apps. Previous attempts (removing
NSMicrophoneUsageDescription, setting com.apple.security.device.audio-input
false in Entitlements.plist) did not suppress the prompt because TCC
fires at AudioUnit instantiation, not at plist level. The upstream fix
in cpal PR #1070 / cpal 0.17 only helps when the pinned device equals
the system default; always-DefaultOutput covers all cases.

Tradeoff: per-device output selection is a no-op on macOS — the stream
always follows the system default. Settings.tsx surfaces this via
audioOutputDeviceMacNotice (hides the CustomSelect on macOS) and skips
audio_list_devices + device-watcher effects there. Matches the behaviour
of Apple Music / Spotify on macOS.

Also removes the now-obsolete com.apple.security.device.audio-input
entitlement (sandbox is disabled anyway, so it was ignored).
