fix(notes): handle time-first due_date phrases in parse_due_for_user (#3319)

parse_due_for_user only matched day-first format ('today at 3pm').
Time-first strings like '3pm today' or '11pm today' — which the tool
schema and tool_index both advertise as valid examples — fell through
all branches, hit dateutil or the legacy _parse_dt fallback, and in
many cases raised ValueError. do_manage_notes then stored the raw
string verbatim, and the ISO-only reminder scanner (action_ping_notes)
never fired the note.

Add a time-first regex branch immediately after the day-first branch
to handle '<time> today|tonight|tomorrow|tmrw|yesterday'. Existing
day-first parsing is unchanged.

Fixes #3302
