Per-project access control + UI/feedback/admin refinements

Access control:
- project_members table; non-admins only see/operate on assigned
  projects (enforced across projects, SOPs, work packages — 403 else),
  admins bypass. Creating a project auto-grants its creator access.
- Admin API to get/set a user's project assignments, plus a checkbox
  assignment dialog in the Admin Console user list.

UI / workflow:
- Login page: drop the "Prime Controls" wordmark next to the logo.
- SOP tool: remove emoji icons from buttons and nav tabs.
- Rename "Step Comments" to "Feedback"; the author auto-populates
  (read-only) from the signed-in user.
- Move usage-log viewing to the Admin Console; add an admin card that
  lists all feedback/comments (who, what, page + step, when).
- Sample project name -> "Micron FMCS Install (sample)".
