PINK: docs v7 + reset_and_seed startup fix — 451/451 tests green

- SYSTEM_BIBLE.md → v7.0: documents fee-sign fix (Defect A), opening-fee
  fix (Defect B), WARN-unfreeze, orphan prevention, reset_and_seed startup,
  and vel_div env-override.
- CAPITAL_BOOKKEEPING_DESIGN.md: status updated to PHASE-1 BUGFIXES APPLIED;
  sections 8.1-8.4 (applied fixes + 34-test coverage) were already present.
- rust_backend.py: expose dita_kernel_reset_and_seed() via _RustKernelLib +
  ExecutionKernel.reset_and_seed(); zeros stale K-accumulators at startup so
  K=E=live_capital → delta=0 → capital_frozen=False on every clean restart.
- pink_direct.py: call kernel.reset_and_seed(live_capital) after
  _restore_kernel_snapshot() so BingX is always the ledger of record.
- launch_dolphin_pink.py: DOLPHIN_PINK_VEL_DIV_THRESHOLD env-var override
  for on-exchange debugging; BLUE unaffected.
