feat(mitm): add connect_action support and implement tunnel blocking

- Introduced `connect_action` function in Roto filters to block or deny tunnels based on pre-defined rules.
- Enabled marking and filtering for blocked tunnels with associated flow metadata (`flow_marks_from_connect_action`).
- Updated dispatcher and runtime to integrate `connect_action` filters and merge their effects.
- Modified TUI and flow event handling to visualize blocked tunnels with customizable labels and colors.
- Enhanced configuration options to disable body limit enforcement and allow unrestricted captures.
- Updated README with details on `connect_action` functionality and its usage in blocking tunnels.
