The mail app’s emoji picker has been renamed from “emojis popover” to “emoji list” in the underlying code and related tests. This makes the feature naming clearer and more consistent for future maintenance without changing how users interact with emojis.

Task-2694206

Odoo now avoids storing the same website and interface view data in two separate caches. This should reduce memory use and unnecessary cache refreshes without changing how users experience the system.

QWeb views are cached two times, first in _compile who itself calls _read_template that is
also cached. The result is a 0% HIT rate on _read_template, and all frontend views are two
times stored in the cache.

Note that _read_template is only used by _compile, and another one in web_studio (that does
not need to be cached). So, removing this cache won't impact the CPU performance, but will
reuce memory usage and LRU invalidations.

This change updates the Mail/Discuss internals to prepare for a newer version of the underlying interface framework. It is a low-risk maintenance improvement intended to keep messaging features compatible and easier to evolve, with no expected change for day-to-day users.

In preparation for using OWL v2 in discuss code.
