Counterpart to RunicGateway/website#76 (role-agnostic /auth/me/* self surface).
- BACKEND_DESIGN.md: add the /auth/me/account* rows to the /auth API contract and
a note that the surface reuses account.controller behind requireAuth (any role),
so a client manages its own account without touching /admin.
- android/PLAN.md: mark §8 item 1 (role-agnostic self-service) DONE and update the
prerequisite-progress summary; version/health (item 4) and branding (item 6)
remain open, push (item 3) is post-v1.
