feat: replace async crypto with sync Rust WASM (port of Baileys b5c1741)

Surgically applies the changes from WhiskeySockets/Baileys commit b5c1741
("feat: replace async crypto with sync Rust WASM" by jlucaso1) while
preserving all custom modifications (interactive messages, carousels,
albums, sticker packs, native flow buttons, Prometheus metrics, etc).

Changes:
- Replace async hkdf/md5 (Web Crypto API) with sync re-exports from whatsapp-rust-bridge@0.5.2
- Replace LTHash class with LTHashAntiTampering from WASM
- Replace mutationKeys() with expandAppStateKeys() from WASM
- Remove ~25 unnecessary await keywords across crypto call chain
- Update Buffer→Uint8Array types for MediaDecryptionKeyInfo and internal crypto functions
- Make noise handshake, media retry encrypt/decrypt, and reporting token generation synchronous

Performance impact:
- Eliminates Promise overhead on every HKDF/LTHash operation
- Significant improvement during app state sync (hundreds of mutations per reconnection)
- Sync crypto reduces event loop pressure under high session load

Custom code preserved (zero conflicts):
- messages-send.ts: All interactive message, carousel, album, sticker pack logic intact
- Types/Message.ts: All custom types (NativeFlowButton, Carousel, Album, etc.) intact
- All Prometheus metrics, circuit breakers, session TTL logic intact
