Refactor `helix/rev2` (#25429)

* Refactor helix/rev2

- Rename rev2 -> beta & update keyboard aliases accordingly
- Removes redundant back, base, sc, under, & qmk_conf revisions
- Removes unnecessary keymaps
- Migrates legacy defines and configuration to keyboard.json
- Tidy's keymap and migrates to JSON
- Fixes RGB configuration to illuminate 32 LEDs per half
- Adds an alternate 4 row layout for snappable PCB
- Tidy's up OLED code
- Enables standard features (bootmagic, extrakey, etc.)
