feat(console): lite backend command-reference modal

Give the lite console the parity analog of the full-node RPC command
reference: the same searchable two-pane modal (browse/search, detail
pane, examples, Insert / Insert & run, destructive confirm), driven by
the lite backend's own command set instead of daemon RPC.

- ConsoleCommandExecutor::commandReference() returns the category table
  (full node = consoleCommandCategories(); lite = new
  liteConsoleCommandCategories() -- 25 backend verbs in 5 categories).
  The shared renderCommandsPopup reads the table from the executor.
- The Commands button now shows for both variants (gated on
  commandReference()!=nullptr); title/tooltip/arg-quoting branch on
  hasRpcReference() (clarified to mean "speaks JSON-RPC / full node").
- Lite args are bare tokens (the backend takes one unsplit arg string
  and does not strip quotes), so the param-builder's JSON string
  auto-quoting is disabled for lite -- Insert & run emits runnable bare
  commands. send uses the JSON-array form (its positional form is
  unreachable via the single-arg transport); new uses zs/R; import
  takes just the key (the backend hardcodes birthday=0).

Adds 7 i18n keys across all 8 languages (additive). Full-node behavior
is unchanged. Adversarially reviewed (data vs the backend registry,
plumbing/regression, i18n) with all findings fixed.
