[BUG] Perl module DB_File missing

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Current Behavior

The DB_File perl module seems to be missing from the official Docker image. The module is needed by the Internal: XMLTV: Italy module to grab EPG data.

When triggering the internal EPG grabbers the following error is returned:

```
2025-12-09 14:36:15.632 xmltv: /usr/bin/tv_grab_it: grab /usr/bin/tv_grab_it
2025-12-09 14:36:15.633 spawn: Executing "/usr/bin/tv_grab_it"
2025-12-09 14:36:15.936 spawn: using cache tv_grab_it.cache
2025-12-09 14:36:15.941 spawn: Can't locate loadable object for module DB_File in @INC (@INC contains: /usr/local/lib/perl5/site_perl /usr/local/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl) at /usr/share/perl5/vendor_perl/XMLTV/Memoize.pm line 73.
2025-12-09 14:36:15.941 spawn: Compilation failed in require at /usr/share/perl5/vendor_perl/XMLTV/Memoize.pm line 73.
```

After running the following the script runs correctly (*) again:

```bash
docker exec tvheadend apk add perl-db_file
```

(*) correct here means that the Perl module missing error is emitted no more; actually no EPG is grabbed, because the grabber seems to be unmantained and non-working...

Can you add back the module to the official Docker image, or consider to remove the Italy grabber plugin altogether?


### Expected Behavior

The script runs correctly, with the following logs:
