fix: mark Advisor tools as project-scoped

[ChiragAgg5k]

Advisor SDK methods call project resources under /reports, but the hidden catalog classified the service as context=console. Hosted calls therefore did not require a project and defaulted to the Console project.

before: advisor_list_reports context=console
 after: advisor_list_reports context=project -> requires project_id

Add Advisor to the project-context policy, update hosted guidance, and assert that every generated Advisor tool carries project context.

This corrects MCP targeting, but production still has a separate downstream blocker: a fresh OAuth token advertises project:reports.read, while targeted /reports calls return missing scopes (["reports.read"]). That scope translation must be fixed in Appwrite Cloud before Advisor succeeds end to end.

Verification

uv run --group dev ruff check src tests
uv run --group dev black --check src tests
uv run --group dev pyright
uv run python -m unittest discover -s tests/unit -v  # 234 passed

Live production probe: users_list succeeded across all six accessible projects; advisor_list_reports reached each project's regional endpoint but consistently returned the downstream reports.read scope error.

Greptile Summary

This PR marks generated Advisor tools as project-scoped so hosted OAuth calls require an explicit target project.

• Adds Advisor to the shared project-context service policy.
• Updates hosted tool guidance to identify Advisor as project-scoped.
• Adds a unit test covering generated Advisor tool context.

Confidence Score: 5/5

The PR appears safe to merge with no actionable defects identified in the changed behavior.

Advisor now follows the established project-context policy in hosted mode, while API-key mode continues using its preconfigured project client without target-context enforcement.
