Drop optional feature gating - SoapySDR hardware support is now required.
Make soapysdr a required dependency in Cargo.toml instead of optional.
Update server to always enable soapysdr backend and its dependencies.
Simplify initialization to always use RealIqSource instead of conditional
fallback to MockIqSource.
This assumes SoapySDR library is installed on the system.

Add RealIqSource that connects to actual SoapySDR devices when soapysdr-sys
feature is enabled. Implements proper device initialization, frequency/bandwidth
configuration, gain control, and RX stream management.
When soapysdr-sys feature is disabled (default), falls back to MockIqSource
for testing. Update feature flags in Cargo.toml dependencies to support both
real hardware and mock operation.
- Device initialization with proper error handling
- RX frequency, bandwidth, and gain configuration
- IQ sample streaming via broadcast channel
- Proper resource cleanup via Drop trait
- Throttled MockIqSource to prevent 100% CPU

Introduces the trx-backend-soapysdr crate with a compilable SoapySdrRig
struct that satisfies the Rig + RigCat trait bounds. RX methods
(get_status, set_freq, set_mode, get_signal_strength) are implemented;
TX-only methods return RigError::not_supported. as_audio_source returns
None for now (overridden in SDR-07). Wires the crate into the workspace
and trx-backend (feature "soapysdr"), and fixes the non-exhaustive match
on RigAccess::Sdr in trx-server main.rs and rig_task.rs.

Add `RigAccess::Sdr { args: String }` to the backend access enum, register
a feature-gated `soapysdr` factory stub in `register_builtin_backends_on`,
handle the new variant in all existing `match` arms, and add the `soapysdr`
feature flag (no dep yet; implementation lands in SDR-04). Mark SDR-02 done.

Move the frontend and backend crate trees to live physically under their
respective binary crate directories, grouping related code together
without merging crate boundaries. Also flatten sub-crate nesting by
moving them out of src/ subdirectories into direct children.
