chore: migrate ESLint to flat config and fix Express 5 / MongoDB driv…

[PierreBrisorgueil]

• Replace .eslintrc.cjs with eslint.config.js (flat config aligned with Vue)
• Replace .prettierrc.cjs with .prettierrc (JSON, drop invalid extends: airbnb)
• Replace eslint-config-airbnb-base + eslint-plugin-import/prettier with @eslint/js + globals
• Simplify lint scripts (remove ./node_modules/.bin/ prefix)
• Fix Express 5: rename app.get('*') to app.get('/{*path}') for path-to-regexp v8
• Fix MongoDB driver 7: store contentType in GridFS metadata (removed from file doc)
• Fix no-constant-binary-expression in config/index.js
• Clean up unused eslint-disable directives and unused catch params

Pull request overview

This pull request migrates the project to ESLint flat config format and addresses breaking changes from Express 5 and MongoDB driver 7 upgrades. However, the PR contains critical issues with package versions that appear to be nonexistent or from the future, suggesting either a significant error in dependency management or an issue with the package.json updates.

Changes:

• Migrated from .eslintrc.cjs to eslint.config.js (flat config) with @eslint/js and globals packages
• Removed Prettier's invalid 'extends: airbnb' configuration and converted to JSON format
• Updated Express 5 catch-all route pattern from '*' to '{*path}' for path-to-regexp v8 compatibility
• Added contentType to GridFS metadata for MongoDB driver 7 compatibility
• Fixed no-constant-binary-expression issue in config/index.js
• Removed unused eslint-disable directives and renamed unused catch parameters to _err
• Updated numerous package dependencies (with version concerns)

• The contentType is being set in both the metadata object (line 16) and the options object (line 21). While this addresses the MongoDB driver 7 breaking change where contentType was removed from the file document, having it in both places may be redundant. Consider whether both are necessary or if only metadata.contentType is needed for MongoDB driver 7.
