ci(labeler): fix nested manifest globs and add api/shared/website area labels

[Wassim Chegham (manekinekko)]

Summary

This fixes PR labeler rules that were dropping labels from Cargo and uv dependency bumps or adding wrong ones elsewhere, and adds three area: labels for parts of the repo that had none.

A scan of all 94 open PRs found these gaps:

• type: dependencies / language: rust: these rules only matched Cargo.toml / Cargo.lock at the repo root, but the gateway's live in apps/gateway/. Because sync-labels: true removes non-matching labels, cargo bumps (e.g. chore(deps): bump quinn-proto from 0.11.14 to 0.11.16 in /apps/gateway #1363) lost type: dependencies on every push. They now match **/Cargo.toml and **/Cargo.lock.
• type: dependencies: now also matches **/pyproject.toml and **/uv.lock (e.g. build(deps): bump pyjwt from 2.13.0 to 2.15.0 in /evaluations/static-prompts #1448, build(deps): bump urllib3 from 2.7.0 to 2.8.0 in /evaluations/static-prompts #1449 in evaluations/static-prompts).
• topic: ui: previously matched all of website/src/**, including docs content and the OpenAPI JSON. It now matches only website/src/{assets,components,scripts,styles}/**.
• New labels: area: api (apps/api/**), area: shared (packages/shared/**) and area: website (website/**). The labels already exist in the repo. The scan found 22, 25 and 11 open PRs touching these paths, none of which had a fitting area label.

Labels on existing open PRs were updated separately; nothing in this PR touches them.

Demos

N/A. Repository configuration only.

Testing

• Parsed .github/labeler.yml as YAML; all 21 label keys load.
• Ran the new globs against the changed files of all 94 open PRs using a minimatch-equivalent matcher. Results matched what was expected, including type: dependencies on chore(deps): bump quinn-proto from 0.11.14 to 0.11.16 in /apps/gateway #1363, build(deps): bump pyjwt from 2.13.0 to 2.15.0 in /evaluations/static-prompts #1448 and build(deps): bump urllib3 from 2.7.0 to 2.8.0 in /evaluations/static-prompts #1449, and no topic: ui on docs-only website PRs such as docs: document model lifecycle and deprecation #1435.

Documentation and compatibility

None needed. CONTRIBUTING.md already defers to .github/labeler.yml for which labels the labeler manages. Once this merges, the labeler will add and remove the three new area: labels automatically on PR pushes, so they shouldn't be applied by hand.
