Fix frozen string crash in new_msg; remove redundant inner titles

Browse Source 
Bug: frozen_string_literal: true makes '' a frozen String literal.
@input << ch raised FrozenError immediately on any keystroke, causing
the TUI runner to exit. Fixed by using +'' (mutable string) for @input
everywhere it is initialised or reset.

Also removed the section header text lines that were being drawn inside
each page's content area — the page title is already embedded in the
right panel's box border, so the inner header was redundant.

Adjusted content offsets and scroll window sizes to use the reclaimed row.
