Advanced Procedural Drum Synthesis & DSP Refinement

[Pitrat-wav]

This PR implements a comprehensive overhaul of the drum synthesis engine based on the provided DSP research report 'Программный синтез аналоговых ударных инструментов: Глубокий DSP-анализ и реализация на базе Web Audio API'.

Key improvements:

1. Authentic Synthesis: Replaced simplified models with circuit-modeled emulations. TR-808 Kick now features a two-stage frequency and amplitude envelope (diode damping). TR-808 Hi-Hats use a 6-oscillator Schmitt trigger matrix.
2. Advanced DSP Utilities: Added generateLFSRNoise (15-bit polynomial x^15 + x^14 + 1) and generateWhiteNoise to DrumUtils.ts for consistent, high-quality noise generation.
3. Micro-Randomization: Every hit now incorporates per-voice pitch drift and decay variance, eliminating the "machine-gun" effect and adding analog warmth.
4. Drum Machine Logic: Added syncInternalParams to DrumMachine for reliable state synchronization. Implemented early exits for zero velocity triggers.
5. UI & UX: Added a randomization (Dice) button to the Drums view, leveraging the Telegram WebApp HapticFeedback API for physical engagement.
6. Technical Debt: Standardized cleanup patterns across all drum classes using onstop/onended events and activeVoices tracking to prevent memory leaks in the Web Audio context.
