Drop redundant "[note]" tag from fundraising-grid note line (v0.1.0:85)

The grid note line was "YYYY-MM-DD [type] Contact: summary"; for the default
"note" type the tag is noise. Omit it for "note"; keep it for informative
types (call, meeting, …). Shared by the Matrix intake bot and grid-UI logging.
Built + installed to the box (installed-version 0.1.0:85, clean 84->85
migration). No schema change.
