Replace the cramped 22-char maint sidebar with a full-width bottom
strip in the same position as logs. Bottom panel is modal: l for logs,
m for maint, same key again to close. Maint strip shows one row per
window with icon, title, affected monitors, and status/time remaining.
Removes maintSidebarW constant and maintOffset field. Introduces
bottomPanel enum (bottomNone/bottomLogs/bottomMaint) replacing
logsOpen and maintOpen booleans. m key no longer gated behind
wideBreakpoint.
