Confirmation dialog wording tweaks
Minor string changes needed:
- Headings should use header capitalization.
- The "document" in the headings seems superfluous?
- "The unsaved changes will be permanently lost." > "The" seems superfluous.
- "The document may have changed since the draft was created and will be permanently lost." > Seems a bit vague and over-complicated.
- "Open documents contain unsaved changes. Changes can be saved or discarded." > Feels abrupt, doesn't elaborate the consequences of not saving.
