## v20260108-29-customer-delete-ticket-remark-scopes
## v20260108-30-customer-delete-ticket-remark-scopes
- Updated customer deletion logic to allow removal of customers that have linked tickets or remarks.
- Added explicit cleanup of related TicketScope and RemarkScope records before deleting the customer.
- Ensured jobs linked to the customer are safely unassigned to prevent foreign key constraint errors.
- Prevented deletion failures caused by existing ticket and remark relationships.

## v20260108-31-inbox-empty-body-attachment-render
- Detect “effectively empty” HTML bodies (e.g. empty HTML skeleton from Graph) and treat them as blank.
- Inbox import: when the Graph body is effectively empty and an EML is stored, extract the first HTML attachment and store it as html_body.
- Inbox message detail: for already-stored messages with effectively empty bodies, dynamically fall back to extracting the HTML attachment from the stored EML so the Inbox popup shows the report without requiring a reset.
