Resolve effect_input/effect_output audio filter pairs (#14241)

* Resolve effect_input/effect_output audio filter pairs

User filter chains can name their input and output nodes differently, so the existing input-name prefix check cannot find their downstream sink. Match effect_output.<suffix> exactly for effect_input.<suffix>, avoiding similarly named filters while retaining prefix-compatible custom tunings and the existing EasyEffects fallbacks.

* Prefer an exact filter output over legacy prefix matches

An earlier stream for a similarly named filter can satisfy the legacy prefix check and select the wrong device before the exact paired output is read. Keep the first prefix candidate as a fallback for effect_input sinks and finish searching for the exact effect_output pair. Preserve first-match behavior for all other sink names.
