fix(android) detekt: shrink AdminUsersScreen, real regenerate fix, suppress TooManyFunctions

The previous push tried to fix detekt but missed two things:

* regenerate() in PlaylistDetailViewModel had its 3 returns "fixed"
  in name only — the if(!refreshable)return was still there. Now
  folded into the variant Elvis chain with takeIf{refreshable}.

* The helper-composable extractions I just shipped pushed three
  screens over detekt's 11-function-per-file cap. Compose screens
  naturally produce many small private composables; per the
  established pattern, suppress TooManyFunctions at the file level
  with a one-line rationale rather than fight the cap.

* AdminUsersScreen main body was 94 lines (cap 60) because I
  rebuilt the Scaffold inline with the new Invites section. Extracted
  AdminUsersScaffold helper so the main function only owns state
  hoisting and dialog dispatch.
