Verify Connect url on board creation

[hadley]

To avoid redirects after the fact. Will (presumably need) https://github.com/rstudio/rsconnect/issues/944.

OTOH I can't reproduce it with this code:

library(pins)

key <- Sys.getenv("COLORADO_CONNECT")

board1 <- board_connect(server = "https://colorado.posit.co/rsc", key = key)
board1 |> pin_write(1:10, name = "hadley/test-1")
board1 |> pin_write(1:11, name = "hadley/test-1")

board2 <- board_connect(server = "https://colorado.rstudio.com/rsc", key = key)
board2 |> pin_write(1:10, name = "hadley/test-2")
board2 |> pin_write(1:11, name = "hadley/test-2")

I get a 403 when writing to board2, possibly some url mismatching in the auth layer. I have rsconnect 1.0.1.

...

Oh but maybe that's because key based auth follows a different path.
