* Fixes two small bugs in the LoginPerSite ui (#7595)
* Restore `providerRequest` message translations (#7600)
This message was removed, but it was replaced with a very similar
message called `likeToConnect`. The only difference is that the new
message has "MetaMask" in it. Preserving these messages without
"MetaMask" is probably better than deleting them, so these messages
have all been restored and renamed to `likeToConnect`.

Co-Authored-By: Mark Stacey <markjstacey@gmail.com>
* Improve disconnectAccount modal message clarity
* Adds cancel button to the account selection screen of the permissions request flow (#7613)
* Fix eth_accounts permission language & selectability (#7614)
* fix eth_accounts language & selectability
* fix MetaMask capitalization in all messages
* Close sidebar when opening connected sites (#7611)
The 'Connected Sites' button in the accounts details now closes the
sidebar, if it is open. This was accomplished by pulling the click
handler for that button up to the wallet view component, where another
button already followed a similar pattern of closing the sidebar.
It seemed confusing to me that one handler was in the `AccountsDetails`
container component, and one was handed down from above, so I added
PropTypes to the container component.
I'm not sure that the WalletView component is the best place for this
logic, but I've put it there for now to be consistent with the add
token button.
* Reject permissions request upon tab close (#7618)
Permissions requests are now rejected when the page is closed. This
only applies to the full-screen view, as that is the view permission
requests should be handled in. The case where the user deals with the
request through a different view is handled in #7617
* Handle tab update failure (#7619)
`extension.tabs.update` can sometimes fail if the user interacts with
the tabs directly around the same time. The redirect flow has been
updated to ensure that the permissions tab is still closed in that
case. The user is on their own to find the dapp tab again in that case.
* Login per site tab popup fixes (#7617)
* Handle redirect in response to state update in permissions-connect
* Ensure origin is available to permissions-connect subcomponents during redirect
* Hide app bar whenever on redirect route
* Improvements to handling of redirects in permissions-connect
* Ensure permission request id change handling only happens when page is not null
* Lint fix
* Decouple confirm transaction screen from the selected address (#7622)
* Avoid race condtion that could prevent contextual account switching (#7623)
There was a race condition in the logic responsible for switching the
selected account based upon the active tab. It was asynchronously
querying the active tab, then assuming it had been retrieved later.
The active tab info itself was already in the redux store in another
spot, one that is guaranteed to be set before the UI renders. The
race condition was avoided by deleting the duplicate state, and using
the other active tab state.
* Only redirect back to dapp if current tab is active (#7621)
The "redirect back to dapp" behaviour can be disruptive when the
permissions connect tab is not active. The purpose of the redirect was
to maintain context between the dapp and the permissions request, but
if the user has already moved to another tab, that no longer applies.
* Fix JSX style lint errors
* Remove unused state
