Should we standardize the `shebangs` for Bash ?

In the code I see different shebangs for shell scripts:

- `#!/bin/bash`
- `#!/usr/bin/env bash`
- `#!/usr/bin/bash`
- `#!/bin/sh`

Start by inventorying the shell-script shebangs across the repository and review the linked references to compare the listed forms. Define whether a single convention is appropriate, then update the affected scripts consistently; done means the chosen standard is applied and documented where relevant.
