fix(tooltip): make Ascension quest-line stripping opt-in (#16)

HideAscensionQuestLines ran on every tooltip and removed any line
matching a quest-objective pattern (N/M, [N] ...), clobbering other
tooltip addons' lines (durability, stack counts, etc.). Gate it behind a
new General-tab option 'Hide Ascension quest progress lines' (default
off) so Questie no longer modifies tooltip lines it does not own by
default. Existing installs read the unset option as off automatically.
