fix: BPF send/send_recv helpers now use AEAD when enabled (#624)

* fix: BPF send/send_recv helpers now use AEAD when enabled

Fixes #622

The BPF helper functions \helper_send\ and \helper_send_recv\ were
calling the HMAC variants (\send_app_data\, \send_recv_app_data\)
unconditionally. With \es-gcm-codec\ enabled by default (PR #615),
the gateway decrypts with AES-256-GCM and silently discards the
HMAC-framed APP_DATA.

Changes:
- \pf_dispatch.rs\: Add AEAD provider storage to \DispatchContext\.
  New \install_aead()\ function passes \AeadProvider\ + \Sha256Provider\.
  Helpers use AEAD when providers are installed, fall back to HMAC
  when not (backward compatible with HMAC-only wake cycle).
- \wake_cycle.rs\: AEAD wake cycle calls \install_aead()\ with the
  \ead\ and \sha\ providers from its arguments. Added \'static\
  bounds on \A: AeadProvider\ and \H: Sha256Provider\ for trait
  object coercion.
- \ead_codec.rs\: Relaxed \Sized\ bounds on \ncode_frame_aead\,
  \open_frame\, and \uild_gcm_nonce\ to accept \?Sized\ providers
  (enables \&dyn AeadProvider\ usage from dispatch context).
- \send_app_data_aead\ / \send_recv_app_data_aead\: Relaxed \?Sized\
  bounds on provider parameters.

* feat: enable debug/trace logging in gateway release builds

Updates GW-1304 to remove compile-time stripping of debug/trace call
sites in release builds. Operators can now enable debug logging on
production gateway binaries via \RUST_LOG=sonde_gateway=debug\ without
recompilation.

The runtime default remains \sonde_gateway=warn\ for release builds.
Node firmware is unaffected (retains \elease_max_level_warn\).

Changes:
- \sonde-gateway/Cargo.toml\: Remove \elease_max_level_info\ from
  tracing features.
- \docs/gateway-requirements.md\: Update GW-1304 AC-2/AC-5 and
  GW-1306 AC-3 to reflect TRACE availability in release.
- \docs... (continued)
