fix(strategy-switch): add crypto_btc_dca to DCA configs + pass through combo_enabled

Threefold fix:
1. Hardcoded DCA_PROFILE_CONFIG (worker.js) and dcaProfileDefaults (index.html):
   - Added crypto_btc_dca with default_mode=fixed, base_investment=100
2. API response: normalizeStrategyProfilesPayload now reads item.dca_enabled
   AND item.combo_enabled from incoming payload, not just hardcoded config
3. Frontend applyStrategyProfiles: reads item.dca_enabled from API alongside
   dcaProfileDefaults fallback

Also synced KV strategy_profiles to latest build from
strategy_profiles_asset.js (via Cloudflare API).
