V1.3.1

v1.3.1 update:
Biggest addition: Cycle tracking. It is optional (off by default, flip it on in Settings); lets you log period start/end dates, flow, mood, and energy, shows your next expected date on the home screen, and has its own history view.

Also added:
-Backdating. Every entry screen now has a Date field with a real calendar picker, so you can log values that you missed from previous days. -Water, Steps, and Sleep also got their own History screens showing last month's total and a yearly average, tucked behind a new save/list icon pair in the bottom bar (Reset stayed as text since it's the one you really don't want to tap by accident).

Bug-wise: fixed the splash screen and launcher icon reverting to plain Android defaults, fixed the keyboard only accepting input once per field, fixed the invert-colors toggle animating backwards, fixed steps reset needing two taps to fully clear, and fixed a sneaky navigation timing issue where a just-entered value could vanish and need to be typed twice before saving.

Heads up: this update adds a new database table for Cycle tracking, and since there wasn't a migration path set up for it, upgrading will reset your existing local water/steps/sleep data. Sorry about that one.
