feat: Bitwarden import bundle + settings search + quick-search hotkey + UX fixes

- Bitwarden CSV import: folders auto-created server-side; notes column on
  login rows surfaces as a "Notes" custom field instead of polluting tags;
  type=card / type=identity rows now mapped to kind=note with the
  credit-card / identity template + card_* / identity_* columns
  pulled into custom_fields; `fields` column parsed (Bitwarden's
  "label: value\nlabel: value" lines + our own JSON shape).
- Settings panel search: live filter at top of the panel, matches each
  .setting-row individually, hides whole section when no row matches,
  shows a "No matches" banner. Esc clears query (without closing
  Settings); Esc with empty query closes the panel.
- Quick-search hotkey customizable: SetQuickSearchHotkey added to
  PM.Bridge; cmd://autofill/hotkeys extended with qs_mods/qs_vk
  (independent of the autofill enabled flag — quick-search stays
  armed even when autofill is off); state.quickSearchHotkey synced
  via settings_json; new "Quick search picker" row in Settings.
- FireDAC SQLite folder POST/PUT: pre-declare ftString on color/icon
  params so .Clear (NULL) doesn't trip "[FireDAC][Phys][SQLite]-335
  type unknown" at Prepare — was crashing the CSV-import folder
  auto-creation path.
- Edge form-data autocomplete suppressed on slideover inputs (title,
  site, username, password, TOTP, note body, custom fields):
  autocomplete=off (new-password on secrets) + spellcheck=false. Fixes
  the "Informations enregistrées" dropdown popping over data after a
  field was edited.
- closeSlideOver blurs any focused descendant before removing .is-open
  so an invisible focused field can't react to arrow-down / backspace
  after dismissal.
- Slideover Esc handler upgraded to capture phase so it fires before
  the input's own keydown or browser-level Esc swallow on the active
  autocomplete popup.
- Settings panel Esc closes the panel when search input is empty;
  search keeps the keystroke when it has a query to clear.
- Discard-fantome on note open: customFields working copy and
  originalCustomJson now share the SAME normalized array — comparing
  raw plainCustom against the .map()'d working copy made notes look
  dirty on open.
- Delete / Backspace global shortcut: batch-trash on normal views,
  batch perm-delete on trash view, gated on selection + no input
  focused + no modal up.
- Toggle thumb vertical centering via top:50% + translateY(-50%);
  state checked uses translate(16px, -50%) to keep the centring.
- Batch bar disappears after per-card restore/perm-delete/trash:
  state.checked.delete(id) before render for the relevant flows;
  state.checked.clear() before render in emptyTrash and the new
  moveEntriesToFolder helper.
