fix: studio createDraft split, llm fallback offers tools, topbar a11y pass

Three Oracle-flagged gaps:

1. Studio createDraft 500 (was masked by retries). Empirical curl
   reproducer proved POST /api/ea2/flow returns 201 with the minimal
   shape but intermittently 500s when config.wizard.* is in the
   initial body. Split: POST creates the draft minimally, then a
   follow-up PUT attaches the wizard config best-effort. Draft
   creation now lands reliably.

2. LLM 'temporarily unavailable' was a dead end for the user. Now
   the assistant returns ok:true with a concrete menu of tools the
   user CAN use right now ('list processes', 'start <name>',
   'open <hub>', 'tell <name> that ...', 'remember ...', 'recall ...').
   The reply renders as a normal assistant message, not a red error.

3. Topbar UI/UX Pro Max pass:
   - Added aria-label to the ⌘K and avatar buttons (icon-only a11y)
   - Removed the duplicate topbar-mid chips on Mission (Mission scene
     already shows family/defName/version inline). Cleaner topbar.
   - Added focus-visible outlines (2px amber, 2px offset) on all
     topbar action buttons + user-menu items
   - Hover/active scale on the avatar (1.04 / 0.97) with 160ms ease
   - Tabular numerals for the ⌘K kbd and notification badge
   - prefers-reduced-motion respected

30/30 vitest pass. tsc + vite build green.
