Replace deprecated rules and remove fix cycles

[Fryuni]

Summary

This pull request updates the ESLint configuration files for both JavaScript and TypeScript, focusing on aligning rules with the latest stylistic plugin conventions, simplifying overrides, and disabling or modifying certain rules for better compatibility and maintainability. The most important changes are grouped below.

Stylistic Rules Migration and Consistency:

• Migrated several core ESLint rules to their @stylistic equivalents, including comma-dangle, function-call-spacing, jsx-quotes, max-len, max-statements-per-line, no-mixed-operators, no-mixed-spaces-and-tabs, and no-tabs in src/configs/javascript.ts for improved consistency and future compatibility. [1] [2] [3] [4] [5] [6] [7] [8]
• Simplified the @stylistic/comma-dangle rule configuration to a single string option.
• Changed @stylistic/quote-props to quote numbers as property names as was previously achieved with the deprecated quote-props.

Rule Removal and Cleanup:

• Removed several deprecated, redundant, or unnecessary rules from the base JavaScript config, such as no-native-reassign, no-return-await, no-negated-in-lhs, valid-jsdoc, require-jsdoc, and various Node-specific rules. [1] [2] [3] [4] [5] [6] [7]
• Removed the override that disabled no-new-object for test files in both JavaScript and TypeScript configs, as the rule is no longer present in the base config. [1] [2]
• Removed the @typescript-eslint/no-empty-interface rule from the TypeScript config as that prevented use of APIs relying on interface extensions.

TypeScript Rule Adjustments:

• Disabled a set of @typescript-eslint rules related to unsafe operations and template expressions to prevent conflicts and allow for more flexible usage of any types where appropriate. Also disabled @typescript-eslint/no-misused-promises due to issues with overloaded functions.

General Configuration Improvements:

• Removed redundant or unnecessary rules and overrides, leading to a cleaner and more maintainable configuration. [1] [2]
• Updated several stylistic and code quality rules for clarity and to better align with project requirements.
