v1.1.0:5 — Gemini model menu correctness

User pointed out their Google AI Studio dropdown shows gemini-3-pro,
gemini-3.1-pro, gemini-3-flash and gemini-2.5-flash — not the longer
preview names I shipped in v1.1.0:4. The menu was missing all the
Flash variants entirely.

Fix:
  - Add gemini-3.1-pro (short form, what AI Studio shows)
  - Add gemini-3.1-flash + gemini-3.1-flash-lite (the cheapest 3.x)
  - Add gemini-3-pro + gemini-3-flash (older tier, still available)
  - Pricing entries for all of the above (~$0.50/$3 per M for Flash)

Pure data fix; no schema or behavior changes.
