depth1 mapcat update

[axf295]

Used claude to update the relevant mapcat integration per mapcat v0.4.0

mapcat's uuid7/datetime/path-rename migrations left this module behind:

• ctime/start_time/stop_time were passed as raw unix-time floats into columns mapcat's "Swapping to datetime" migration made datetime, causing session.commit() to raise "SQLite DateTime type only accepts Python datetime and date objects" on the very first commit_depth1_tods call (outside the mapmaking try/except, so it hard-crashes the pipeline before a map is made).
• commit_depth1_map passed time_path, a field DepthOneMapTable no longer has (split into start_time_path/mean_time_path/end_time_path). SQLModel silently drops unknown kwargs, so no time-map path was ever recorded.
• commit_depth1_tods passed map_name into TODDepthOneTable, which has no such column anymore (association is via a many-to-many relationship through TODToMapTable). The kwarg was silently ignored, so TODs were never actually linked to their map.

Verified against a real mapcat db migrated to head: commit succeeds, ctime/start_time/stop_time land as datetimes, mean_time_path is populated, and the TOD<->map relationship is linked in both directions.
