[BUG] MMB click in the notifications page goes to home

[TomW1605]

Describe the bug

Middle Mouse Button (MMB) click in the notifications page goes to home not the relavent card

How can we reproduce the behavior

have a notification and MMB click on the link to the card/issue in either the hover dropdown or the main notifications list

Workarounds

the only real work around is to open a new tab manually and navigate to the relevant issue from scratch but that doesn't clear the notification (see #159)

Screenshots

Taiga environment

Self hosted, docker
no error logs

Desktop (please complete the following information):

• OS: Windows 11
• Browser: Chrome
• Version: 131.0.6778.109

Additional context

it looks like the issue is here. the ng-click doesn't catch the MMB click event and the blank href direct it to the home page.

it should be possible to achieve this by switching this to ng-mouseup/ng-mousedown and handling each button directly. however using javascript to open a new tab without focusing (thus replicating the correct behaviour for MMB click) can be a pain.
i think a better option would probably be to fix issue #159 so that viewing a card/issue will clear any notifications relevant to that item and then the link in the notifications list can be a simple link and does not need handling with javascript
