fix(tui): clamp log sidebar width, strip redundant prefixes

Log lines now hard-clamped to panel width via lipgloss MaxWidth.
Stripped "Monitor " and "Push " prefixes from sidebar messages —
redundant in a monitoring app, saves 8 chars per line. Improved
prefix width calculation to prevent line wrapping at narrow widths.
