GymForge: Workout Tracker

- Typing a weight or increment now works as expected: decimal points no longer disappear mid-entry and values stay put until you're done typing. - Switching to a variant exercise mid-workout now suggests a load from that exercise's own history instead of carrying over the previous exercise's weight. - The load direction arrow now also appears when editing past workouts, comparing each session against the one before it. - Opening an exercise to edit it no longer silently changes its load or flips the direction arrow. - Personal records are only counted once a workout is completed, and a workout that runs past midnight now lands on the day it finished. - The workout summary no longer lists the same personal record twice. - Fixed a Live Activity that could linger on the Lock Screen after starting a new workout. - Fixed rare crashes when starting a plan with an exercise set to zero sets, and a freeze in the Plate Calculator with very large target weights. - Workout history export now filters correctly when only a start or end date is set.
