[Feature]: Improve analytics consent and label clarity

[openhands-agent]

What problem or use case are you trying to solve?
Would you please consider delaying any analytics connections until the user gives explicit consent? Also, the "Enable analytics" label could be clearer—for example, in Italian, and likely in other languages, it becomes "Enable analysis", which on its own is a bit unclear. Something like "Share anonymous usage data" would translate better.

Desired UX of the solution
Labels like "Share anonymous usage data" which have better translations across languages and functionality to delay analytics until explicit consent is given.

Technical implementation
Translate label string across various internationalization files and add logic to delay analytics connections until consent.

Alternatives considered
