Subject: [PATCH] Fix bulk edit and insert date field handling

- Bulk edit: only include changed fields in update payload so unchanged
  date fields are not overwritten with null
- Bulk edit: normalize datetime oldValue to date-only for correct comparison
- Insert form: pre-fill date/datetime fields with today's date by default
