- Line 97: Update addTimerRow() and the removal flow around rTR() so adding a
timer reuses an available index from T0 through T15 instead of relying on the
ever-increasing timerCount. Preserve existing timer groups and ensure newly
created groups remain within the WLED_MAX_TIMERS range.

Reuse a freed timer index after removal.
addTimerRow() allocates the next timerCount value, while rTR() does not decrement it. After 16 timers, removing one and adding another creates T16. set.cpp parses only T0–T15 when WLED_MAX_TIMERS is 16, so the new timer is ignored. Reuse a freed index or renumber the remaining timer groups before submission.

Remove the "Delete Timer" list entry which was confusing and use a "-" button instead.
