Audio Phase 3 (AUDIO_FIDELITY F9/F11/F12): EFX lowpass + reverb split + cockpit placement

Browse Source 
New L4AUDEFX bridge (OpenAL Soft ALC_EXT_EFX): one EAXReverb aux slot at the
authentic AUDIO.INI global_reverb_scale (0.3) + a scratch AL_FILTER_LOWPASS
(params copied at attach).

F9 filters (was: computed then thrown away -- everything full-bright at all
distances): Dynamic3D ExecuteModel drives GAINHF from highFreqCutoffScale x
brightnessScale x maxMIDIFilterCutoff, UNGATED (decomp part_008.c:7496,
7589-7604 -- every moving 3D sound dulls with distance per the AUDIO.INI
knee-60/exp-2.0 model); Static3D from brightness x max (:7831-7884); Direct
inside its existing gated NRPN-rate block.  AWE 100-8000 Hz curve -> EFX
5 kHz-reference gainhf via a 2-pole approximation [T3 curve, endpoints exact].

F11 reverb (was: bone-dry everywhere): 3D patch sources attach an aux send at
Start, exactly where the original sent CC91 = global_reverb_scale
(part_008.c:7278-7394); Direct cockpit sources keep CC91=0 -- dry.  The
wet-exterior vs dry-cockpit contrast is back.

F12 placement (was: every cockpit sound dead-center): DirectPatchSource
Start places sources by the authored 6-value position enum (front/rear card
+ pan CC10, decomp @00463848/@004638a8) as listener-relative directions,
composed with the zone L/C/R pan.  New PatchResource GetBankID/GetPatchID
pass-throughs (the LOD accessor is protected).

Regression (35s drive+fire): EFX READY, stable, deliveries unregressed, no AL
errors.
