When a post in an archived topic has no existing likes, the backend omits the li…ke entry from `actions_summary` (no count, no `can_act`, no `acted`), making `likeAction` null on the frontend. Core's like button handles this correctly (renders as disabled), but the reactions plugin — which replaces core's like button — had guards that checked `likeAction && !(canToggle || can_undo)`. When `likeAction` was null, the guard was bypassed, allowing clicks that triggered a 403 from the backend with a misleading "too long ago" error message. Posts with existing likes were unaffected since `likeAction` existed with `canToggle: false`, and the guard worked as intended. This commit: - Flips the `toggleFromButton` guard from `likeAction && ...` to `!likeAction || ...` so null likeAction blocks the interaction - Reorders the `toggle()` condition to check `likeAction?.canToggle` first, preventing reactions via the emoji picker - Adds an early return in `pointerOver` when `!likeAction?.canToggle` to prevent the reaction picker from opening on hover - Adds optional chaining in the picker's `reactionInfo` getter to fix a TypeError crash on `post.likeAction.canToggle` when null - Uses the server error message in `_extractErrors` when available instead of a hardcoded misleading string, and updates the fallback translation to a generic message https://meta.discourse.org/t/399681
