Respect inline translate style for single-message Translate and preserve link entities

[Rocket-Space]

Motivation

• Single-message Translate menu still opened the popup dialog even when the translator style was set to On Message, causing unexpected UI behavior.
• Translating via the popup caused loss of user-created text links/entities; the inline translation pipeline already masks and restores entities.

Description

• Added import of TranslationHelper and a new helper method tryTranslateMessageInline(MessageObject, String) in ChatActivity that invokes TranslationHelper.translateMessage(...) when SpaceGramConfig.translateStyle == 0 and a non-Telegram provider is selected.
• Updated the three single-message Translate entry points in ChatActivity to call tryTranslateMessageInline(...) first and only fall back to TranslateAlert2.showAlert(...) when inline translation is not applicable.
• This reuses the existing inline masking/restoring logic to preserve MessageEntity links when translating on-message.
• Modified file: TMessagesProj/src/main/java/org/telegram/ui/ChatActivity.java.

Testing

• Attempted to compile Java with ./gradlew -q :TMessagesProj:compileDebugJavaWithJavac, but the local environment failed with a JDK/Gradle mismatch error (Unsupported class file major version 69), so a successful build could not be validated locally.
• Performed local code inspection and search (rg/sed) to verify the new callsites and the presence of the new helper method; no runtime tests were executed due to the environment compile failure.
