feat: placeholder support, download fix, table exclusion modes, log viewer, detail view

- Add PlaceholderResolver for [host], [date], [profile_name], etc. in
  backup_dir and new archive_name_format profile field
- Fix download ERR_INVALID_RESPONSE by flushing output buffers before
  sending file headers
- Table exclusions now have separate Data and Structure checkboxes
  (backward compatible with existing newline format)
- Backup log files written alongside archive for posterity
- Log viewer modal in backup records list and inline in detail view
- Clickable record description links to detail view with checksum,
  file path, DB size, and full log
- Dashboard health check shows actual resolved backup directory path
- Fix update site link to use list view (avoids Joomla core bug)
- Schema migration 01.01.09 for archive_name_format column
