v2.19.1

Bug Fixes

• discovery: crop a server banner before uploading it. The icon and avatar uploads
  have always opened a crop editor; the banner was the only one that took the raw file
• discovery: the server description field was styled as a single-line input, so it
  rendered as tall as the name field however many rows it asked for. It is a proper text
  area now, and the discovery card shows four lines of description instead of two,
  scrolling when there is more
• db: editing a server description failed with an internal error, and a message's old
  text stayed searchable after it had been edited. Both came from pruning an
  external-content FTS index with a plain DELETE, which rebuilds the terms to remove from
  a content row that already holds the new value
• ws: don't raise the reconnect banner for the short reconnect that follows unlocking
  a phone — it finishes well before there is anything worth reporting
