fix: add visible key to frontmatterToEntryPatch maps

The ENTRY_DELETE_MAP and update map in frontmatterToEntryPatch were
missing the 'visible' key. When handleDeleteProperty or
handleUpdateFrontmatter was called for 'visible', the in-memory
VaultEntry was not updated, causing the sidebar to stay stale even
after the file on disk was correctly modified.
