Subject: [PATCH] fix: ensure config directory exists before mkstemp in
 _write_config_snapshot

AstrBotConfig._write_config_snapshot calls tempfile.mkstemp(dir=directory)
without verifying the directory exists. When a config profile is created
for the first time (e.g. create_conf instantiates AstrBotConfig with a
brand-new path), __init__ calls save_config before the directory is
guaranteed to exist, and mkstemp raises FileNotFoundError.

Add os.makedirs(directory, exist_ok=True) before mkstemp. This is the
standard defensive pattern for atomic-write helpers.

Fixes three intermittently-failing dashboard tests:
- test_t2i_set_active_template_syncs_all_configs
- test_t2i_reset_default_template_syncs_all_configs
- test_t2i_update_active_template_reloads_all_schedulers

Closes #9855.
