fix: resolve critical bugs - disciplines, debug reset, floating point, spire loop

Fixes:
- Issue 193: Remove unnecessary useEffect that set activeTab when spireMode is true, and redundant setAction('climb') in SpireCombatPage
- Issue 194: Fix signed_pact prerequisite check in checkDisciplinePrerequisites by accepting signedPacts param; add 'At Limit' feedback on discipline button when concurrent limit reached
- Issue 195: Add resetDisciplines(), resetAttunements(), resetCrafting() calls to createResetGame; add resetCrafting action to crafting store
- Issue 196: Fix floating point display in ElementStatsSection (mana pools) and GameStateDebug (time); fix duplicate 'Base Regen' label in ManaStatsSection

All 917 tests pass. Files stay under 400-line limit.
