Ryan Malloy 7d48398551 Add FM downlink mode: carrier blocks, convenience wrappers, and loopback demo ...

FM mode now has the same three-layer architecture as PM mode:
- fm_mod/fm_demod for carrier-level FM modulation
- fm_signal_source/fm_downlink_receiver convenience wrappers
- fm_loopback_demo.py verifying round-trip SCO voltage recovery

Includes GRC YAML for all 4 blocks and doc updates across
blocks reference, SCO guide, and signal architecture pages.
