fix(deps): upgrade outdated Rust dependencies across services

stream-server (Cargo.toml):
- sqlx 0.7 -> 0.8
- redis 0.25 -> 0.27 (fix query_async generic args in revocation_store.rs)
- bcrypt 0.15 -> 0.17
- thiserror 1.0 -> 2.0
- dashmap 5.5 -> 6.1

veza-common (Cargo.toml):
- sqlx 0.7 -> 0.8 (required to avoid libsqlite3-sys link conflict)
- thiserror 1.0 -> 2.0

chat-server (Cargo.toml):
- sqlx 0.7 -> 0.8 (alignment with veza-common)
