Build: Refactor Webpack config to TS (#121181)
* build(webpack): add tsconfig.json for Node strip-types compliance

* build(webpack): extract shared esbuild options to esbuild.ts

* build(webpack): add package.json to declare ESM module type

* build(webpack): convert sass.rule to TypeScript

* build(webpack): convert CorsWorkerPlugin to TypeScript

* build(webpack): convert FeatureFlaggedSriPlugin to TypeScript

* build(webpack): convert webpack.common to TypeScript, add theme entries

* build(webpack): convert webpack.dev to TypeScript, remove esbuild duplication

* build(webpack): convert webpack.prod to TypeScript, remove esbuild duplication

* build(webpack): fix TypeScript types in webpack.prod transform callback

* build(webpack): convert webpack.stats to TypeScript

* build(webpack): update scripts to use TypeScript webpack configs

* build(webpack): simplify env-util to use import.meta.dirname directly

* build(webpack): tidy up plugins

* build(webpack): move rules for ts and sass into single module

* build(webpack): consolidate shared config into common, move splitChunks to prod

- Move MiniCssExtractPlugin, esbuildRule and sassRule into common so both
  dev and prod configs share them without duplication
- Move splitChunks/runtimeChunk optimisation to webpack.prod only (not
  needed in dev)
- Use require() for SubresourceIntegrityPlugin to work around broken ESM
  build (waysact/webpack-subresource-integrity#236)
- Refactor conditional plugin logic in dev from ternary to if-blocks

* build(webpack): remove dead import and clarify webpack destructure pattern

- Remove unused MiniCssExtractPlugin import from webpack.prod (moved to common)
- Add comment explaining why DefinePlugin/EnvironmentPlugin are destructured
  from the default webpack import rather than using named ESM imports

* style(webpack): reorder consts

* chore(env-util): fix up env-util and webpack configs so tests continue to run

* refactor(env-util): accept grafanaRoot param instead of relying on __dirname

Removes the global.__dirname mutation hack in webpack.common.ts by making
the grafana root path an explicit argument to getEnvConfig. Each caller
resolves its own root and passes it in, removing the implicit path-depth
contract and the CJS/ESM compatibility workaround.

* build(webpack): remove unused angular chunk group
