* fix(core): strip quotes from MCP server header keys and values
Users pasting JSON-formatted env vars into MCP server config end up with
quoted header names like `"CONTEXT7_API_KEY":` which causes
httpx.LocalProtocolError. Sanitize keys (strip surrounding quotes and
trailing colons) and values (strip surrounding quotes) in
resolve_custom_headers, resolve_environment_variables for HTTP configs,
and stdio env dicts.

* fix: revert stdio env sanitization to pass-through
The stdio path doesn't need header/env sanitization - that's only
relevant for SSE/streamable HTTP servers with auth headers.

fix(LET-4053): clean up old mcp client code
Remove commented-out and unused files in functions/mcp_client:
- Deleted base_client.py (fully commented out)
- Deleted sse_client.py (fully commented out)
- Deleted stdio_client.py (fully commented out)
- Deleted empty __init__.py
Kept types.py and exceptions.py as they contain active code still being used.
