fix(checklists): Bring MP behavior in sync with XP/Gold

Previously, the player would accrue Mana for every checklist item when a To-Do was completed, regardless of whether or not those checklist items were complete. This was inconsistent with XP and Gold, which were only multiplied based on the number of checklist items previously clicked. Now Mana acts the same way, multiplying MP scored by (1 + completed checklist items).

Replace hard-coded strings for window.env.t on js files
Fixed stealth display, added mock dailies (for stealth calculations), forced buffs to reset after each test; also changed stats to be more reflective of potential max stats.
Stealth scales with # of dailies as well as per; currently avoids 100% of dailies at 100 total per.
