Add "Ehlers" prefix to 5 Ehlers indicators: SAM, PMA, ILRS, CTI, RVGI

Standardize naming convention so all Ehlers-originated indicators
have "Ehlers" in their display name across all documentation and
code surfaces:

- SAM: Smoothed Adaptive Momentum → Ehlers Smoothed Adaptive Momentum
- PMA: Predictive Moving Average → Ehlers Predictive Moving Average
- ILRS: Integral of LinReg Slope → Ehlers Integral of LinReg Slope
- CTI: Correlation Trend Indicator → Ehlers Correlation Trend Indicator
- RVGI: Relative Vigor Index → Ehlers Relative Vigor Index

Updated across: .md H1 titles, XML doc summaries, Quantower Name
properties, Quantower test assertions, _sidebar.md, lib/_index.md,
category _index.md files, docs/indicators.md, docs/validation.md.

Build: 0 warnings, 0 errors. All tests pass.
