feat(bb_pub): lazy heap-backed store-forward ring by default, static-BSS behind CONFIG_BB_PUB_BUFFER_STATIC (B1-489) (#659)

- default (STATIC=n): ring pool owns a right-sized heap arena via
  bb_pool_create_owned, created lazily on first use and destroyed after
  IDLE_FREE_TICKS idle ticks (restores the pre-PR-D ~0-standing-cost
  lifecycle, now via bb_pool); a failed heap allocation is fail-soft
- STATIC=y: keeps the PR D permanent static-BSS bb_arena shape (~8.5 KB
  standing, no heap alloc, no idle-free reclaim)
- track the live pool's actual backing via s_ring_pool_is_static instead of
  re-deriving the mode at cleanup time, since bb_pub_test_reset() runs twice
  per test (global setUp + local buf_reset) and the test-seam override can
  disagree with the pool already in memory between those calls
- add host tests for lazy-heap zero-standing-cost, alloc+reclaim heap-stats
  delta, fail-soft alloc failure, and STATIC=y parity
