fix: i18n button text stripping and German translation corrections (v0.42.1)

Three sidebar buttons (+ New job/skill/profile) and three suggestion
buttons had data-i18n on the outer element, causing applyLocaleToDOM
to strip the + prefix and emoji characters when switching locales.
Fixed by wrapping only the label text in a <span data-i18n=...>.

Also corrects German translations:
- cancelling: imperative -> progressive (Wird abgebrochen...)
- editing: first-person verb -> noun (Bearbeitung)
- empty_subtitle: add missing 'explore files' clause
- settings_desc_check_updates: add git fetch detail
- settings_desc_cli_sessions: add 'continue the conversation' clause

+### Bug Fixes
+- **i18n button text stripping** (post-review): Three sidebar buttons (`+ New job`, `+ New skill`, `+ New profile`) and three suggestion buttons had `data-i18n` on the outer element, which caused `applyLocaleToDOM` to replace the entire `textContent` — stripping the `+` prefix and emoji characters on locale switch. Fixed by wrapping only the translatable label text in a `<span data-i18n="...">`.
+- **German translation corrections** (post-review): Fixed `cancelling` (imperative → progressive `"Wird abgebrochen…"`), `editing` (first-person verb → noun `"Bearbeitung"`), and completed truncated descriptions for `empty_subtitle`, `settings_desc_check_updates`, and `settings_desc_cli_sessions`.
