test(e2e): migrate runner to uv, add All Proxy Models key test (#28313)

* chore(e2e): migrate runner to uv, add All Proxy Models key test

Switches the local e2e runner (run_e2e.sh) from poetry to uv to match
the rest of the repo and CI. Adds a Playwright test for creating an
admin key with no team selected (all-proxy-models flow), a SLOWMO env
hook for headed debugging, and a MIGRATION_TRACKING.md doc that maps
the manual UI QA checklist to e2e tests so future migration work has
a single source of truth.

* chore(e2e): address greptile feedback

- Remove MIGRATION_TRACKING.md (docs belong in litellm-docs repo)
- playwright.config.ts: fall back to 0 when SLOWMO is non-numeric
  (parseInt returns NaN, which Playwright accepts silently)
- run_e2e.sh: add --frozen to uv sync for CI determinism
