The user-menu's Profile link previously 404'd, and CRM users had no way
to change their password from inside the app.
- /api/v1/me/password POST wraps better-auth changePassword, surfaces a
friendlier "Current password is incorrect" on the typical failure
mode, and writes an audit_log row with metadata.revokedOtherSessions.
- /{port}/settings/profile renders display name + email + change-password
card with current/new/confirm fields and a 'Sign out other devices'
toggle.
End-to-end verified: wrong current pw → 400 with mapped message;
correct → 200 + audit row; revert → 200.
