Proposed changes

The first test of Quelea 0.2.0 on the team proxy worked, but the messages look flat. /party shows a grey wall of text, commands cannot be clicked, and success, errors and hints look the same. Translations are fixed to English and German inside the jar, so even a colour tweak needs a release.

This change proposes three things:

• A consistent palette: the existing brand gradient for headers, green for success, red for errors, amber for hints, and a gold star for the leader.
• A clickable help: a click suggests the command, and hovering explains it.
• Open translations: the plugin picks the bundle by client language and country, and operators can drop messages_<lang>.properties files into plugins/quelea/lang/ to add a language or override single messages. Missing or broken keys fall back to English.

Redirecting chat into the party with @ or a toggle is deliberately left out. It needs SignedVelocity on the proxies plus a Minestom backend part, and gets its own change.

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation Update (if none of the other choices apply)

Checklist

• I have added tests that prove my fix is effective or that my feature works
• I have added necessary documentation (if appropriate)

Further comments

Ships as feat(velocity): give party messages colour, clickable help and open translations. Adventure's GlobalTranslator was considered and rejected in the design.
