fix(profiles): keep validate_profile_name strict; callers normalize first

Follow-up to @changchun989's cherry-pick: reverts the validate-via-
normalize change so validate_profile_name remains a strict regex check
on the input AS-GIVEN. Callers that accept mixed-case user input
(dashboard UI, CLI args, import flows) call normalize_profile_name()
first, then validate the result. This keeps validate honest about
what the on-disk directory name must look like — e.g. '  jules '
(trailing whitespace) is now rejected instead of silently trimmed
and accepted.

- validate_profile_name: strict lowercase/regex check again, 'UPPER'
  back in the invalid-names parametrize
- 8 call sites in profiles.py (create_profile, delete_profile,
  set_active_profile, export_profile, import_profile, rename_profile,
  resolve_profile_env, plus the clone_from branch): swap the
  normalize-then-validate order
- scripts/release.py: add changchun989@proton.me -> changchun989 to
  AUTHOR_MAP so CI doesn't block on the unmapped contributor email

All kanban + profile tests pass (268 across test_profiles.py +
test_kanban_db.py + test_kanban_core_functionality.py, plus 73 in
test_kanban_tools.py + test_kanban_dashboard_plugin.py).

Closes #18498.
