feat(creation): the character creation screen

Variant C of the mock: seven nameplate calling cards in one row, with the chosen
calling's blurb AND mechanics in a detail panel below — the one card you
committed to is the only one that talks.

Editor-first (ADR 0001): the tree is in the .tscn, the script binds. No rules
here — CreationDraft holds them, CreationCopy derives the display strings, the
prose comes from ContentDB. Emits creation_confirmed(Dictionary); M4-c
constructs. Five ability cards. Never six (§7).
