refactor(scripts): split monolithic module into per-script submodules

Extract shared `mkScript` and `mkScriptModule` helpers into `lib.nix`
Split each script into `modules/scripts/<name>/` with its own
  `default.nix`, `script.sh`, and `assertions.nix`
Remove `conditions` parameter from `mkScriptModule`; move condition
  assertions into per-script `assertions.nix` files with inline checks
  and error messages
Simplify `mkScriptModule` to return `{ options, moduleConfig }` instead
  of a module function, taking `config` as a direct parameter
Add `description` field to `mkScript` that inserts the description as
  a `# <text>` comment between the shebang and env vars
Thread `description` through `mkScriptModule` to each `default.nix`
Move top comment lines from each `script.sh` into the `description`
  field and remove from sources to avoid duplication
Remove old flat `.sh` files from `modules/scripts/` root
