fix(tui): defensive mouse-report sanitizer and move provider-wait logging off render path

Strip SGR mouse coordinate tails even when mouse capture is disabled, covering
orphaned terminal reporting state after crashes or focus races (#3063/#3067).

Move provider-wait incident logging from footer render to the main tick loop
so stall diagnostics do not fire on every redraw (#3095 harvest note).
