feat: message reactions detail redesign

[arnautov-anton]

🎯 Goal

BREAKING CHANGE: MessageReactionsDetail's (formerly ReactionsListModal) composition (markup) has changed, class names have been renamed or removed (see table bellow). It no longer renders in a modal but rather in a dialog - this change required a container-agnostic rename.

Removed	str-chat__message-reactions-details-modal	-
Changed	str-chat__message-reactions-details	str-chat__message-reactions-detail
Changed/Restructured	str-chat__message-reactions-details-reaction-types	str-chat__message-reactions-detail__reaction-type-list-container + str-chat__message-reactions-detail__reaction-type-list
