Add post-processing audio effects system

Adds a full effects pipeline powered by Spotify's pedalboard library, enabling users to apply professional DSP effects (flanger, reverb, delay, compressor, pitch shift, filters, gain) to generated audio. Key features: - Effects chain editor with drag-and-drop reordering (dnd-kit) - Generation versions: clean copy always saved, processed versions created on top - Built-in presets (Robotic, Radio, Echo Chamber, Deep Voice) + custom user presets - Per-profile default effects chain (auto-applied to new generations) - Per-generation effects override from the generation form - Apply effects to existing generations from history (creates new version) - Ephemeral preview endpoint for auditioning effects without persisting - Dedicated Effects sidebar tab with preset management and live preview - Version switcher in history cards with expandable panel - Backward-compatible: existing generations backfilled as clean versions
