fix #394 #395 #396: OP8 re-gate round — caption font, retail key names, capture dialog

Three findings from the user's first Configure Keyboard look (OP8 gate,
2026-08-14), each root-caused against the named retail decomp:

- #394 row-caption font: the synthesized action-label UiText never set
  DatFont and fell to the debug bitmap font. The authored row template
  (0x21000009/0x1000002F, retail UIOption_ActionKeyMap) carries FontDid
  0x4000000A (18px serif) — Bind now takes resolveTemplateFont and applies
  the template's own authored font, resolved once per template pair.

- #395 key captions: raw enum spellings ("Shift+ShiftLeft") replaced by the
  port of CInputManager_WIN32::GetNameFromKey @0x00687F40 /
  GetNameFromKey_Internal @0x00687800 (RetailKeyNames): DAT string-table
  override by DIK-name hash (key enum 4 -> 0x2300000A, meta enum 5 ->
  0x2300000B, delimiter enum 3 -> 0x23000007 — GetDIDByEnum category 4,
  live-probed), else the OS keyboard layout's own key name ("SKIFT") via
  PlatformKeyNameProvider (Win32 GetKeyNameTextW — register row AD-96 for
  the DirectInput-vs-GetKeyNameText adaptation), else the DIK-suffix
  spelling. Bare modifier-key bindings show only the key name.

- #396 capture feedback: clicking a mapping button now opens retail's
  instruction dialog (InitiateBinding @0x004899D0 -> OpenMapWarnDialog
  @0x00488A00): a type-2 WAIT dialog on retail's MapWarn queue key
  0x10000001 with ID_ActionKeyMap_MapInstructions (0x23000004, ACTION
  variable interpolated), closed on key hit or ESC through the capture
  callback; capture is not armed if the dialog cannot open, matching
  retail. New RetailWaitDialogView (wait root 0x31 — same authored
  popup/message pair 0x3D/0x3E as the confirmation root, live-DAT probed)
  behind a shared IRetailDialogView presenter seam.

Probe evidence (env-gated, kept):
KeyboardConfigLiveMountProbeTests.ProbeKeyboardFontsAndKeyNameStrings.
Register: AD-96 filed. Gate script OP8 section updated (step 4 rewritten;
the "pressed/active state is enough" contract is retired).

Full Release solution suite green (13,424 passed / 4 skips).
