Fix order of RPC and wallet keys fetched from env vars

[lukaszcl]

This commit refactors the code in lib/config/env.go to use sorted keys when handling environment variables. Previously, the code was iterating over the environment variables in an arbitrary order, which could lead to inconsistent behavior. Now, the getSortedEnvs function has been added to sort the environment variables by key before processing them.

Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

The changes ensure consistency and predictability in how environment variables are read and processed by sorting them alphabetically. This facilitates better organization and potentially makes debugging easier when dealing with a large number of environment variables.

What

• lib/config/env.go
  • Added import of sort package to enable sorting functionality.
  • Introduced a new utility function getSortedEnvs which sorts environment variables by their keys before returning them. This function is now used in place of direct calls to os.Environ() in ReadEnvVarSlice_String, readEnvVarGroupedMap, and readEnvVarSingleMap functions.
    • This change ensures that environment variables are processed in a consistent order, which is particularly useful for functions that depend on the order of environment variables, such as when generating slices or maps from them.
