chore: remove duplicated emoji css

[ricardogarim]

Proposed changes (including videos or screenshots)

RocketChat/fuselage#2086 moved the emoji font-size/line-height rules into fuselage's own styles (MessageReactions, Messages, ThreadMessage). With that version bumped in, the matching overrides we keep in emoji.css are now duplicated, so this removes them:

• .rcx-message-reactions__emoji size rules
• .rcx-message__emoji font-size/line-height
• &--big size rules (incl. big custom-emoji dimensions)

Kept on purpose (not covered by fuselage): the .rcx-message__emoji font-family, the global .emoji / picker rules, and .emoji--custom dimensions (image-based custom emojis still need explicit sizing).

Issue(s)

• CORE-2411

Steps to test or reproduce

1. Bump @rocket.chat/fuselage to the version including PR fix(fuselage): Adjust sizings for unicode emojis fuselage#2086.
2. Send a message with only unicode emojis (big emojis), a message with inline emojis, an emoji reaction, and a custom (image) emoji.
3. Confirm all render correctly and unicode emojis are vertically aligned in message, reaction, and thread views.
