chore: move ae_events_functions.ts into ae_events/ module

Relocates the functions file from lib root into its module directory,
matching the pattern used by all other modules (ae_journals, ae_archives, etc.).
Updated all 85 import paths from \$lib/ae_events_functions → \$lib/ae_events/ae_events_functions.
