Display admin id with sent messages

context

it is sometimes difficult to know which admins are doing what in a signalboost channel - who is sending a private message, who is responding to hotline messages and who broadcasting messages. we want a way to ID admins without exposing their identities.

behavior

private replies

• when an admin, bob, sends PRIVATE blah blah blah
• then all the admins see a message that says

[PRIVATE FROM ADMIN 1]
blah blah blah

• when alice sends PRIVATE beepity boopity
• then all the admins see a message that says

[PRIVATE FROM ADMIN 2]
beepity boopity

hotline messages

• when a hotline message comes in that looks like

[HOTLINE @1012]
would packaged snacks be helpful?

• then alice responds REPLY #1012 yes that would be great!
• then all the other admins see:

[REPLY @1012 FROM ADMIN 2]
yes that would be great!

broadcasts

• when alice sends a broadcast message community meeting happening now!
• then all other admins see:

[BROADCAST FROM ADMIN 2]
community meeting happening now!

implementation

• add a counter column to the channel table called nextAdminId
• add a column to the memberships table called adminId

when a new admin is added

• take the value from nextAdminId and assign it to the newly created admin membership
• increment nextAdminId
• add [ADMIN ID] in messenger#addHeader

questions

• do we need #'s?
• do other command behaviors need to say who is doing what? vouching/hotline on? (not squeaky)
