refactor(surfer): reconcile live funding deploy onto cross-sectional construction

The cockpit ran TWO funding tracks: 'funding' (absolute 5bp-hurdle, long-only, faithful
port of crypto_funding_paper.py) and 'xsfunding' (cross-sectional long-top/short-bottom,
delta-neutral). Investigation (regime-switch backtest) showed the absolute-hurdle variant
sits idle ~60% of days and was flat through 2022, while the cross-sectional construction
harvests funding DISPERSION, trades continuously, and made +71% in the 2022 backtest
(LUNA/FTX deleveraging dispersion). The two were a confusing parallel where the conservative
one masqueraded as the dormant crown jewel.

Retire the absolute 'funding' track (asset funding_nav, registry entry, job membership) and
promote 'xsfunding' as the canonical funding deploy (relabelled 'Crypto funding harvest
(cross-sectional, delta-neutral)'). FundingCarryStrategy stays in paper_strategies.py
(tested, on the shelf) — only the live deploy changes. Tests updated (12 assets now);
full suite 499 passed, mypy clean on changed lines.
