feat(settings): global Advanced Mode toggle + playlist page layout (#556) (#720)

Adds a per-element visibility toggle for the playlist detail page (Add
Songs, Import CSV, Download ZIP, Cache Offline, Suggestions) and reworks
the way uncommon options are surfaced: instead of a per-tab collapsible
group, a global "Advanced" toggle in the Settings header reveals all
`advanced` sub-sections across every tab and marks each one with a small
badge. Sets the pattern up so any future advanced option lives in its
natural tab, gated by the same switch.

- New `advancedSettingsEnabled` boolean on `authStore`
  (UiAppearance slice, persisted with the rest of the store).
- `SettingsSubSection` gains an `advanced?: boolean` prop. Hidden when
  the toggle is off; renders an "Advanced" pill in the header when on.
- Settings header gets a Toggle-Switch next to the search lupe.
- `PersonalisationTab` flattens — Sidebar + Home stay always visible;
  Artist sections, Queue Toolbar, and the new Playlist layout get
  `advanced` and disappear by default. `PersonalisationAdvancedGroup`
  component + CSS removed.
- New `playlistLayoutStore` (Zustand + persist, items[{id,visible}] +
  rehydrate sanitize) following the queueToolbarStore pattern.
- `PlaylistHero` and `PlaylistSuggestions` gate the four toolbar buttons
  and the suggestions rail on the store directly.
- One-time migration in MainApp on mount: if the user had opened the
  old per-tab Advanced group (`psysonic_personalisation_advanced_open
  === 'true'`) OR already customised any of the three sub-sections,
  Advanced Mode auto-enables on first launch. Idempotent via a
  localStorage flag; legacy key removed afterwards.
- New i18n keys `settings.advancedMode`, `settings.advancedModeTooltip`,
  `settings.advancedBadge`, `settings.playlistLayout*` in all 9 locales.

Reuses kveld9's design from PR #556; not merged because the locale split
landed afterwards. Credited under the existing kveld9 entry in
settingsCredits.ts.

+### Settings — Advanced Mode toggle + playlist page layout
+
+**By [@kveld9](https://github.com/kveld9) + [@Psychotoxical](https://github.com/Psychotoxical), PR [#556](https://github.com/Psychotoxical/psysonic/pull/556)**
+
+* **Advanced Mode.** A new toggle in the Settings header reveals advanced sub-sections across all tabs. Sub-sections marked advanced are hidden by default and labelled with a small badge when shown — community-contributed options that do not necessarily reflect the design philosophy of the Psysonic maintainers, kept available but out of the way. The three current advanced sub-sections live under **Personalisation**: Artist page sections, Queue Toolbar, and the new Playlist page layout.
+* **Playlist page layout.** New sub-section that hides individual elements on the playlist page: **Add Songs**, **Import CSV**, **Download ZIP**, **Cache Offline**, and the **Suggestions** rail at the bottom. Persisted via a new `playlistLayoutStore` (Zustand + localStorage); all toggles on by default so existing playlists look unchanged.
+* **One-time migration:** if you had previously opened the per-tab Advanced group or customised any of the three sub-sections, Advanced Mode is auto-enabled on first launch — your existing tweaks stay visible.
+* i18n: `settings.advancedMode`, `settings.advancedModeTooltip`, `settings.advancedBadge`, and `settings.playlistLayout*` across all 9 locales.
