Implementation of import/export functionality for favourite servers list

[itsneufox]

This PR adds functionality to export and import favorite server lists.

Changes:

• Added two new buttons in the Advanced settings section:

  • Export favorites list to file
  • Import favorites list from file

• Added necessary translation strings for both English and Portuguese languages

• Included error handling for various scenarios:

  • No favorites to export
  • Invalid file format
  • File access errors

Details:

• Export format uses JSON with a version compatibility marker (currently version 1) to allow for future format changes.

Example omp_servers.JSON:

{
  "version": 1,
  "servers": [
    {
      "ip": "99.999.999.999",
      "port": 7777,
      "name": "MACACO RP | 1",
      "password": ""
    },
    {
      "ip": "99.999.999.999",
      "port": 7777,
      "name": "MACACO RP | 2",
      "password": ""
    },
    {
      "ip": "99.999.999.999",
      "port": 7777,
      "name": "MACACO RP | 3",
      "password": ""
    },
    {
      "ip": "99.999.999.999",
      "port": 7777,
      "name": "MACACO RP | 4",
      "password": ""
    }
  ]
}

Also, as commented on discord, dll-syringe is broken on the latest rust nightly.

I used rustc 1.87.0-nightly (794c12416 2025-02-21)

As discussed on discord, removed server names to avoid encoding issues, also added fetchServers(true) to force an update to the list.

🎉🎉
Now dll-syringe is fixed.

I want to thank my mother for believing in me and Dobby for letting me steal SAT source code...

Thank you.
