MAINT-11 review round 2: pin each cycle button to its own disabled flag

Reviewer mutations survived the round-2 page checks: Start forced always
disabled (|| true), and the two flags swapped between Start and Stop,
because the checks only looked for each flag somewhere in the file. The
check now pins each flag to its own button. No behaviour change.
