feat: Real-time location on the map

[BalloonWinter53]

Closes #1708

⚠️ The feature must be tested on iOS (and, if needed, Web/MacOS/Windows/Linux) before merging.

Nice work! Works as expected, but consider these changes:

• disable de proximity circle around the main location dot.
• change the location dot color and the gyroscope color to uni red.

Apart from that, one member with an iOS device will take on this PR to fix the permissions on those devices. Thanks!
