fix(roles): remove unused roles, merge managers, revoke Clerk's ALL_FUNCTIONS

Audited role usage/permissions across all tenants and cleaned up several
inconsistencies:

- Removed 'Self Service User' (zero users, no wired-up purpose in the app).
- Merged 'As Manager' into 'Branch Manager' (union of both permission sets,
  users reassigned, As Manager dropped) since the two covered overlapping
  ground with no clear split.
- Revoked Clerk's ALL_FUNCTIONS grant: it unconditionally bypassed every
  individual permission check (HasPermissionDirective), so unticking any
  menu/permission for Clerk in Roles & Permissions had no effect. Clerk's
  own explicit permission rows are untouched and remain the effective set.
- Renamed 'CASHIER' to 'Cashier' for display consistency with every other
  role name; the role-name check this touches (CashierRoleHelper) is
  case-insensitive, so behavior is unchanged.

('Principal Officer' was audited too but kept - it's the statutory
PMLA/RBI compliance seat from 0435, just not yet assigned to anyone.)

Each change was applied directly to all three tenant DBs and captured as
a migration (0543, 0546, 0547), dry-run verified as a no-op against the
now-updated DBs so it applies cleanly here and correctly for any new tenant.
