fix: store opened_at and closed_at as DATETIME (not DATE)

DATE columns lose time information, causing timeline to show 00:00 for
car reception and WO closure. Migrated both columns to DATETIME and
updated: model casts (date → datetime), form pickers (DatePicker →
DateTimePicker with seconds:false), default to now() instead of today(),
and cleaned up defensive Carbon::parse() in getTimeline().
