fix(console): localize the lite console + drop full-node-only wording

The lite console tab lagged the full-node one on i18n: its toolbar status,
status lines, help, and error/warning strings were hard-coded English or
worded for a full node (a "daemon" the lite wallet doesn't have).

- toolbarStatus()/statusLines(): route through TR() (reusing the existing
  lite_net_* keys where they already map)
- printHelp(): enumerate the 25 pass-through backend verbs for discoverability,
  since the C++ tab intercepts `help` before the backend's own HelpCommand runs
- gate the destructive 'stop' confirmation to the full node (hasRpcReference);
  lite has no node, so it lets 'stop' fall through to the backend instead of
  showing a phantom "shut down the node" warning behind a dead gate
- word the not-connected error per variant (daemon vs "no wallet open")
- TR() the "(no output)" command-result fallback

Adds 7 i18n keys across all 8 languages (additive); rebuilds the CJK subset
for the one new glyph (U+C5D4 for the Korean "backend"). Build + ctest +
source-hygiene green; changes adversarially verified (no logic/i18n defects).
