Preserve archive frame IDs during calibration registration

[timbeccue]

Problem

Some calimages entries set frameid == NULL even when the frame exists in the archive. This happens when the database is updated via add_super_calibration or add_bpms_from_archive:

• Importing existing BPMs from the archive, e.g. banzai_populate_bpms --db-address "$DB_ADDRESS"
• Uploading a manually prepared calibration frame

banzai_add_super_calibration /path/to/readnoise.fits \
    --db-address "$DB_ADDRESS" \
    --upload-to-archive

• Re-importing a calibration whose database ID was already correct

Changes

• Pass the Archive response’s id into DataProduct in add_bpms_from_archive.
• Pass the ingester response’s frameid into DataProduct in add_super_calibration
• Removecal_image.frameid assignment in add_super_calibration (looks like dead code?)

Registering an existing filename without uploading continues to set its archive ID to NULL. Existing NULL rows remain unchanged.

Validation

• Added two regression tests covering BPM import and super-calibration registration with and without upload.
