feat(runtime) Campaign CA CA3 #431: live derived-stat recompute — a raise is visible without a relog

The recompute half of #431, on the CA1 verdict that retail computes
derived values LIVE at inquiry (Set* writes raw; InqSkillBaseLevel
0x00592140 -> SkillFormula::Calculate 0x00591960 re-derive per call;
InqRunRate 0x00592800 runs every motion tick; UI notifications carry no
value and widgets re-pull):

- LocalPlayerState gains the SkillTable formula resolver — the same
  delegate shape (and App-side implementation, RetailSkillFormula over
  the loaded SkillTable) the PlayerDescription path already uses. An
  attribute write re-derives every skill snapshot's cached formula
  contribution; recomputing at the only write that changes the inputs
  yields values identical to retail's compute-on-read at every read. A
  freshly TRAINED skill unseen at login derives its contribution live
  instead of defaulting to zero forever.
- The router pushes movement-skill totals down the SAME seam
  PlayerDescription uses (UpdateMovementSkillBase -> vitae/enchantment
  recompute -> OnSkillsUpdated -> the App stats applier) after an
  attribute update, and after a skill update for Run (24) / Jump (22)
  only. This is what turns a Quickness raise into visible run speed
  mid-session; the server's own movement-packet echo
  (HandleRunRateUpdate -> ApplyServerRunRate) remains the correcting
  authority.
- Vitals maxima needed no new plumbing: GetMaxApprox reads attribute
  currents live and the vitals window binds getter lambdas re-read per
  frame, so CA2's attribute fan-out completes that path. The character
  panel already subscribes to AttributeChanged/CharacterChanged.

Tests: router behavior test drives the real WorldSession events through
the real router and asserts the full chain (state write, live 160/2=80
re-derivation, movement push totals, and that a non-movement skill does
NOT push); the subscription-count contract now includes the two new
events; Core tests cover the fresh-train resolver derivation. Full
hermetic suite 15,335 passed / 0 failed.
