Improve performance when inspecting the large request response

[NghiaTranUIT]

Description

Proxyman might be unresponsive if we inspect the Request/Response, in which the body size is bigger than 20Mb.

Acceptance Criteria

• In the Body Tab: Don't display the large body (>= 5Mb) -> Suggest to "Export to File" or "Show Anyway"
• In the Raw Tab: Automatically trimming the raw body (>= 5Mb)
• Avoid app crashes
