refactor: one copy of the UI's repeated helpers

- Text inputs come from newTextInput; the link and folder prompts share one width.
- One starred-first sort for sources, vaults and secrets; accountOf where the account was cut from the label by hand.
- One helper each for the reveal and clipboard countdowns' tick and seconds, the "Open with" choices, the vaults-loaded count, and Go to's and the panes' tabs.
- The details pane builds its label prefix, indent, note and source once; list rows mark matches with MarkMatches.
- The release page opens through openPage, so it now says it opened, as other pages do.
- The cache's account filter is built once per load or save, not per key.
