refactor(i18n): route remaining Obsidian UI text through the message catalogue

Continues the source-key migration inside the application boundary introduced
in 1.0.0, where LiveSync owns its catalogue and consumes Commonlib as a
published package.

- Replace hardcoded user-visible strings in the Obsidian UI (Setup Wizard
  dialogues, P2P panes, Customisation Sync panes, Global History, the JSON
  conflict pane and the remote-configuration menu) with `$msg` calls, keeping
  the English source string as the key.
- Wire up strings whose translations already existed in the catalogue but were
  still rendered as literals, for example the whole Intro dialogue.
- Add the new entries to `src/common/messagesYAML/en.yaml` and `es.yaml`, then
  regenerate `messagesJson/` and `combinedMessages.prod.ts` through the
  documented `i18n:bake` pipeline.
- No Commonlib gitlink or catalogue is involved; every change is
  LiveSync-owned.

Regenerating the catalogue also normalises three pre-existing entries each in
`ko.json` and `zh.json`, where the committed JSON kept a trailing space before
a newline that YAML cannot represent.

Verified with tsc-check, tsc-check:apps, svelte-check and lint.
