jgrusewski 8b9abcc3c1 fix: resolve all clippy errors across 37+ workspace crates
Eliminate ~4,260 clippy deny-level errors that blocked workspace-wide
clippy runs. Errors cascaded: upstream crate failures (ctrader-openapi,
risk-data) hid thousands of downstream errors in ml, tli, backtesting.

Key changes:
- ctrader-openapi: fix shadow_unrelated/shadow_reuse (renamed vars)
- risk-data/risk: replace non-ASCII em dashes with ASCII equivalents
- tli: allow deny lints on prost-generated proto code, fix shadows
- trading_engine: fix let_underscore_must_use, wildcard matches, shadows
- broker_gateway_service: allow dead_code on unused redis_client field
- ml (4030 errors): remove local deny overrides for unwrap/expect/indexing
  (workspace warn level sufficient), add crate-level allows for non-safety
  mass-violation lints (non_ascii_literal, shadow_*, str_to_string, etc.),
  batch-fix em dashes, unseparated literal suffixes, format_push_string,
  wildcard matches, impl_trait_in_params, mutex_atomic, and more
- backtesting: replace unwrap() on first()/last() with match destructure
- tests: simplify loop-that-never-loops, fix mutex unwrap
