Refactor and reorganize validation policy checks in BalsaFrame.

- Nest `disallow_invalid_request_methods` inside method defect evaluators to eliminate redundant condition checks in `ProcessFirstLine`.
- Decouple `IsInvalidHeaderKeyChar` from `IsInvalidHeaderKeyCharAllowDoubleQuote` pathways in `FindColonsAndParseIntoKeyValue` to streamline validation pipelines while preserving fallback conformance blocks.
- Group validation against combining Transfer-Encoding with Content-Length upstream directly inside Transfer-Encoding decode pipelines in `ProcessHeaderLines`.

No behavioral changes were introduced to standard frame processing hooks.
