Miha Kralj ef00330de3 fix: sort all _index.md indicator tables alphabetically 
Fixed sort order in 4 files:
- lib/_index.md: AMFM, PTA, USI/USF repositioned (421 total)
- lib/cycles/_index.md: ACP moved to correct alphabetical position
- lib/oscillators/_index.md: DPO/DSO swap, RRSI/RSIH/RVGI reordered
- lib/numerics/_index.md: NORMALIZE/NORMDIST swap

# Oscillators
Oscillators fluctuate above and below a centerline or within bounded ranges. Useful for identifying overbought/oversold conditions, momentum shifts, and divergences. Best in ranging markets; trend-following indicators work better in trending markets.
