refactor: split api.py monolith into 19 route modules (Phase B)
Split 3,598-line api.py into thin orchestrator (128 lines) + 19 route
modules in bot/routes/:
core.py (7 routes), mood.py (10), language.py (3), evil_mode.py (6),
bipolar_mode.py (9), gpu.py (2), bot_actions.py (4), autonomous.py (13),
profile_picture.py (26), manual_send.py (3), servers.py (6),
figurines.py (5), dms.py (18), image_generation.py (4), chat.py (1),
config.py (7), logging_config.py (9), voice.py (3), memory.py (10)
All 146 routes verified present via test_route_split.py (149 tests).
21/21 regression tests (test_config_state.py) pass.
Monolith backup: bot/api_monolith_backup.py (revert: cp it to api.py).
