Potential fix for https://github.com/codetheuri/Tusk/security/code-scanning/10

To fix the problem, we need to ensure that the value parsed from the string fits within the range of a uint before casting. The best way is to check that the parsed id is less than or equal to math.MaxUint (which is architecture-dependent), and only then perform the cast. If the value is out of bounds, return the zero value and false to indicate failure. This change should be made in the GetUserIDFromContext function in pkg/auth/token/interface.go. We will need to import the math package to access math.MaxUint.

Incorrect conversion between integer types High

Incorrect conversion of an unsigned 64-bit integer from strconv.ParseUint to a lower bit size type uint without an upper bound check.

To fix the problem, we need to ensure that the conversion from uint64 to uint is safe and does not result in truncation or overflow. The best way is to check that the parsed value fits within the range of the platform's uint type before converting. Since the size of uint is platform-dependent, we can use ^uint(0) to compute the maximum value of uint at runtime. The check should be if id <= uint64(^uint(0)), which ensures that the value fits in a uint on any platform. Additionally, we should remove the use of the undefined math.MaxUint. No new imports are needed.

The only change required is in the GetUserIDFromContext function in pkg/auth/token/interface.go, specifically the check on line 52.
