Highlight detection result data with MicroLighter

Description

Highlight the JSON in the "Data" field of the detection result detail page with MicroLighter, instead of EasyAdmin's code editor field.

• <micro-lighter language="json" controls="copy" line-numbers> from the microlighter npm package (MIT, about 2 kB gzipped), registered in assets/admin.js with the GitHub theme. It highlights with the CSS Custom Highlight API, so it adds no markup per token, and it gives the field line numbers and a Copy button.
• The theme follows EasyAdmin's light/dark switch (ea-light-scheme / ea-dark-scheme on <body>) rather than the OS setting its light-dark() colours use.
• The element loads grammars with import(./grammars/${language}.js) relative to the bundle, which Vite leaves as is. Reprise's copy option ships the 40 grammar files unhashed in public/build/grammars/; only json.js is fetched.
• The field uses a new code_highlight.html.twig template with a language custom option, so it can be reused for other code.
• DetectionResult::getPrettyData() now encodes with JSON_UNESCAPED_SLASHES and JSON_UNESCAPED_UNICODE, so paths and URLs read https://github.com/... instead of https:\/\/github.com\/....
