* fix(macro): replace hardcoded BTC mining thresholds with Mayer Multiple
The $60k/$40k thresholds were calibrated for 2023 BTC prices and
always return 'PROFITABLE' at current price levels. Use the Mayer
Multiple (price/SMA200) instead — this adapts to any price regime.
Falls back to dollar thresholds only when SMA200 is unavailable.
Addresses #197 (L-11).

* refactor(macro): rename Mining Cost → Price Momentum, use Mayer Multiple
- Replace hardcoded $60k/$40k thresholds with Mayer Multiple (price/SMA200)
- Reuse existing `mayerMultiple` variable instead of recomputing
- Remove stale hashChange guard — momentum doesn't depend on hashrate
- Drop dollar fallback; return UNKNOWN when SMA200 unavailable
- Rename signal: MiningCost → PriceMomentum, statuses: STRONG/MODERATE/WEAK
- Update proto, OpenAPI specs, generated types, frontend panel, all locales
