Eliminate diceware channel names
value
- after getting rid of channel names and descriptions (see #380 (closed)) we ran an experiment to provide channels with diceware names in order to provide a memorable but random identifier for a channel
- however, we received feedback that the diceware names were confusing + distracting to subscribers of these channels, and did not provide much added utility or security benefits
- thus, we will remove them!
behavior
GIVEN an admin who has just created a channel
- THEN an admin will receive a welcome message that suggests they (1) store the number as a contact in their phone
GIVEN a subscriber who has just joined a channel
- THEN the subscriber will receive a welcome message that suggests they store the channel number as a contact in their phone
GIVEN a message is broadcast on a channel
- THEN there will not be a channel name in the header
GIVEN anyone sends INFO to a channel
- THEN they will not see either a channel name in the response
GIVEN a visitor to the splash site
- THEN they will not see a reference to "channel name"
implementation
- migration to remove channel names
- deleting header code + tests that include channel names
