feat: add gr-foo, gr-owc, gr-dab to OOT module catalog

New installable modules:
- foo: Wireshark PCAP connector, burst tagger (bastibl, maint-3.10)
- owc: Optical Wireless Communication simulation (UCaNLab, main)
- dab: DAB/DAB+ digital audio broadcast receiver (hboeglen, maint-3.10)

gr-dab requires fdk-aac-dab (bundled subdir) + libfaad-dev at build time.
gr-foo is a dependency of the already-cataloged gr-ieee802-11.

Catalog now has 22 modules (12 preinstalled, 10 installable).
All 3 new modules built and verified in Docker.
