Feature request: Add Custom User-Agent or GET URL Parameter for Tonkeeper Browser

[Totemancer]

Is your feature request related to a problem? Please describe.
In the previous version of the app, the parameter ?utm_source=tonkeeper was automatically appended to all visited websites. This functionality is missing in the current version, making it challenging to identify traffic originating from the Tonkeeper browser and, therefore, to create a better experience for users and visitors from the app.

Describe the solution you'd like
Reintroduce the automatic addition of the ?utm_source=tonkeeper parameter to all URLs accessed through the Tonkeeper browser. Alternatively, implement a custom User-Agent string, such as Tonkeeper Android/[AppVersion], to clearly identify the browser and enhance user experience with decentralized applications (dApps).

Additional context
Implementing a custom User-Agent string or reintroducing the URL parameter would facilitate better analytics and optimization for dApp developers, leading to an improved experience for all Tonkeeper users.
