Address Obsidian review bot feedback

Fix issues flagged by the Obsidian plugin review bot on PR #12037:

- configSerializer: guard stat widget value against object stringification
- UI strings: apply sentence case to button labels and descriptions; use
  canonical SQL casing
- dashboardRenderer: drop redundant HTMLElement|null assertion on
  parentElement
- linkWidget: mark openLinkText promise as intentionally unawaited
