Final-pass polish: support contact UX, audit tooltip, doc refresh

Support teams: contact management moved from a row expander to a modal
(Contacts (N) button per team); application detail Support card and the
modal show Email (mailto) and Teams chat buttons for contacts with an
SSO, derived as sso@ + a new contact_email_domain site setting
(default geaerospace.com, blank hides the buttons).

Audit log: hovering a user SSO shows the full name, resolved
best-effort from the employee directory in either mode.

Docs/hygiene from a standards review: CLAUDE.md active-state,
CONTRACT-STABILITY.md and README brought to contract 0.10.0 / 11
plugins / migration head 7d22; get_asset_panels endpoint path fixed in
the hook docstring; leftover debug console.logs removed.

781 tests pass; contacts modal, action-button hrefs, and the audit
tooltip verified live.
