[Feature]: Custom Stickers + Emojis and Emoji Reacts

[kolacheee]

What problem does this solve?

Give convo mode (ONLY) a more d*scord-like feel.

Proposed solution

1. Implement persona galleries (like how characters have their own) + global gallery (idk where is best to put this, maybe just a tab in Settings?)

• Add a tooltip to galleries that images must be below ?x? size to be an emoji or sticker

2. Inside the character, user, and global gallery add a toggle when moused over to enable the image as an emoji and place it in the Convo mode emoji selector

• Images that are too large to shrink instead flash red with a too large warning

3. Inside the character, user, and global gallery add a pencil where the user can rename the image (in the prompt, the emojis will display as :emojiname: rather than the actual image since not all models that people use can see images)
4. in CONVO MODE ONLY, add sticker selector (custom emojis can go inside the native emoji selector)
5. in CONVO MODE ONLY, images from galleries can be linked into sticker and emoji selectors (so persona can have unique stickers/emojis, and bots can have unique stickers/emojis, and/or anyone can use stickers/emojis from common gallery)

• users will need to be able to name stickers and emojis

6. in CONVO MODE ONLY, persona and bots can react to messages with stickers and emojis that they have access to, which are visible in prompt when chat history is scanned
7. UNDECIDED - should emoji reacts have a chance of triggering a response?

Note: Emojis, emoji reacts, and stickers must be visible in the prompt so that the LLM users utilize can register them and use them. Emojis will appear as :emojiname: in the prompt, and stickers as sticker:stickername:

Note: All personas and characters have access to emojis and stickers in the global gallery. Emojis and stickers in persona galleries can only be accessed by the persona whose gallery it resides it. Emojis and stickers in character galleries can only be accessed by the character whose gallery it belongs to.

Started this in #2361 — the gallery foundation the rest of the feature builds on:

• Persona galleries (point 1): a Gallery tab on personas, mirroring the existing character gallery.
• Global gallery (point 1): a dedicated top-level Gallery panel with flat folders + sorting, rather than a Settings tab.

That PR is management-only and intentionally does not close this request. The remaining parts are planned as follow-up PRs:

• Emoji/sticker model — enable-as-emoji/sticker toggles, pencil-rename to :name:, and the size validation + "too large" warning (points 2 and 3).
• Conversation-mode-only emoji + sticker selectors and sending (points 4 and 5).
• Conversation-mode-only AI reactions, visible in the prompt as :emojiname: / sticker:stickername: (point 6).

Point 7 (whether emoji reacts have a chance of triggering a response) is still parked as undecided.
