Changes
* Update FIXME in userMenu.less to merge selectors
* We replace minerva-user-notifications class with minerva-notifications
to short-circuit Echo's code so that it no longer replaces the Minerva
notification badge with its own.
* We update resources/skins.minerva.scripts/initMobile.js to introduce
our own wire up code - this is responsible for opening Echo overlay
and reseting the counter. The code in Echo will be removed in a follow
up (see <I2f923e509d24524a2375ffbe6b3ef336487574bb>)
* We update skinStyles/ext.echo.styles.badge.less with styles from Vector 2022
so that Minerva desktop remains consistent with desktop Vector 2022 experience.
* We clearly mark technical debt relating to the special mobile version.
Testing:
* Pixel.js has a group echo that covers all the different variants.
Make sure to update to latest main branch before running these.
* Desktop should behave the same for Minerva as Echo.
* On mobile only when a user has unseen notifications a red circle
is shown. Otherwise a bell icon is shown, never with number.
* On mobile a single button is visible that combines alert and count
numbers.
* With Echo disabled a bell shows that links to the user talk page
Visual changes:
* Previously the red circle became a transparent/gray circle on click. Now
it will always be red.
* Minor aligment changes to red circle and bell icon are expected as
the change prevents MobileFrontend/Echo updating the icon to use
Codex.
