Theseus 0.3.118: drop Phind (Vercel 404), re-bundle AI picker icons

Phind's web UI returns a Vercel 404 at the root as of 2026-10-27, so
users who clicked Open AI with Phind as the default got a dark error
page. The engine is now marked frozen with a reason, which keeps the
Settings row visible with an explanation but takes it out of the
enabled list; anyone whose defaultLlmId was phind automatically falls
back to the next enabled engine (Perplexity).

AI picker icons move from runtime favicon fetch back to bundled files
(ChatGPT, Grok, Gemini return as engine-icons/*.svg — initial-on-color
tiles). The fetch path still runs as a fallback for custom engines and
anything else that lacks a bundle.
