Three action-factories peel ~25 setters out of the authStore body,
following the playerStore action-factory pattern from Phase E:
- `createServerProfileActions` — `addServer`, `updateServer`,
`removeServer` (the non-trivial one — drops every per-server map
entry for the removed id), `setServers`, `setActiveServer`,
`setLoggedIn`, `setConnecting`, `setConnectionError`, `logout`.
- `createAuthLastfmActions` — credentials + session connect/disconnect
+ error flag + master scrobbling toggle. Network calls (love /
scrobble) stay in the playerStore-side `lastfmActions.ts`.
- `createAudioSettingsActions` — replay-gain / normalization /
loudness mode toggles (each calls `usePlayerStore.getState()
.updateReplayGainForCurrentTrack()` so a running track catches up),
plus crossfade / gapless / hi-res / audio-output (no engine
callback needed).
Pure code-move; no behaviour change. authStore.ts: 518 → 428 LOC (−90).
