chore(release): v1.28.19 — document and card polish

Documents vault card: date + size and an AI-read marker now sit directly under
the title instead of the meta line running off under the thumbnail.

Document detail view: a larger close control replaces the small X and the
redundant top-right shortcut; the inline read-with-AI row under the preview is
gone (the suggest / summarise / show-text actions stay); a button to ask about
the document sits next to share and download.

Mental-wellbeing cards no longer wash the whole tile on hover — only the title
is the open target, matching the medication cards.

Medication API settings render inline instead of behind an expander that never
had anything beside it.
