Avoid stuck dimming when translating a single message

[Rocket-Space]

Motivation

• Prevent the chat UI from remaining dimmed/unresponsive after using the Translate message context action by making sure per-message translation uses the same UI flow as full-chat translation.

Description

• Change tryTranslateMessageInline in ChatActivity to always return false, removing the inline shortcut so callers fall back to the existing TranslateAlert2 flow that properly handles dim/undim lifecycle; removed the unused TranslationHelper import.

Testing

• Ran a local compile attempt with ./gradlew :TMessagesProj:compileDebugJavaWithJavac -x lint, which failed due to the environment JDK/Gradle incompatibility (Unsupported class file major version 69).
• Verified the change was staged/committed via git status --short and git show --stat --oneline HEAD.

Preserve inline translation for "On Message" style

This unconditional return false removes the only inline path for per-message translation, so when SpaceGramConfig.translateProvider != 0 and users select the "On Message" translation style, the context action now always falls back to TranslateAlert2 popup flow. That is a behavior regression for a user-configurable feature (style setting is still exposed in SpaceGram settings), not just a dimming lifecycle change.
