feat(ui): Bookmark tab content + CharacterProfile signal payload (Workstream 6)

Fills in the Bookmark tab stubbed in W5 with the full spec from
Araminta: card list + detail view + start-button gating. Also changes
the creation_confirmed signal to carry a CharacterProfile instead of
bare CharacterVisualDescriptor, consolidating bookmark + location
selection into one payload object.

Bookmark tab (left pane, 35%):
- ScrollContainer over VBoxContainer of card Buttons, one per entry in
  GameState.bookmark_catalog. Each card: title (PRIMARY_TEXT,
  font_header 15px) / subtitle (DIM_TEXT, font_small 10px, clipped) /
  career badge (ACCENT_ACTIVE, all-caps). Selected state uses existing
  ITEM_SELECTED_BG + ITEM_SELECTED_BORDER. custom_minimum_size
  Vector2(180, 64).

Detail view (right pane, 65%):
- ImplantPanel composed via add_component:
  - ImplantHeader (bookmark.title, bookmark.subtitle)
  - ImplantSeparator
  - ImplantTextBlock (flavor, autowrap, PRIMARY_TEXT)
  - ImplantSeparator
  - ImplantDataRow CAREER (accent_active) / CAPITAL (accent_positive,
    format "%d Tractus") / STARTING LOCATION
  - ImplantSeparator
  - [location picker space reserved — W7 fills it]

Selection:
- Card click stores _selected_bookmark_id, auto-assigns
  _selected_location_id from bookmark.default_location, rebuilds
  detail view.
- Start button (footer) gated on both _selected_bookmark_id and
  _selected_location_id non-empty.
- Randomize while Bookmark tab is active picks a random bookmark +
  one of its allowed_locations and skips appearance randomization.

Signal contract change:
- creation_confirmed(profile: CharacterProfile) replaces
  creation_confirmed(descriptor: CharacterVisualDescriptor).
- CharacterProfile now extends RefCounted (was Resource) with
  non-exported fields — it's a one-shot signal payload, never
  persisted. This also sidesteps the scanner error that the prior
  @export var descriptor: CharacterVisualDescriptor on a Resource
  caused (RefCounted types cannot be @export-ed).
- _on_start emits a CharacterProfile built from _descriptor +
  _selected_bookmark_id + _selected_location_id, then sends
  ConfirmBookmark via SimBridge.send_named_action before scene
  transition.

Test updates:
- test_character_creation_sprint28.gd signal receivers switched to
  untyped to accept CharacterProfile without hitting class_name
  parse-order at test-suite scan time. 88/88 pass.

Verification:
- gdlint clean
- godot --headless --path client --quit — no SCRIPT ERROR (prior
  character_profile.gd scanner noise now gone after the RefCounted
  conversion)
- test_character_creation_sprint28 88/88, test_protocol 62/62,
  test_implant_nav_stack 52/52

Workstream 7 (location picker as sub-component of the Bookmark detail
view) follows. W8 fills the Skills tab.
