fix(wm): dynamically reserve monitor ring space

This commit makes a small change to dynamically keep reserving space in
the VecDeque that backs Ring<Monitor> until an index preference can be
contained within the current length.

This commit also fixes some clippy lints and adds some allow
annotations.
