Replace Prettier with OXFmt

[sweptsquash]

This pull request focuses on standardizing and improving code formatting and linting across the project. The main changes include replacing Prettier with Oxfmt for code formatting, updating linting rules for stricter code quality, and making minor import order adjustments for consistency. Additionally, several test files have been updated to ensure consistent import ordering.

Formatting and Linting Improvements:

• Added a new .oxfmtrc.json configuration file for Oxfmt, specifying formatting rules and import sorting groups, and removed Prettier configuration and ignore files. [1] [2] [3]
• Updated package.json scripts and dependencies to use Oxfmt instead of Prettier for formatting, and upgraded Oxlint and related packages. [1] [2]
• Enhanced .oxlintrc.json with stricter linting rules by enabling prefer-const and no-var, and refined ignore patterns for better coverage. [1] [2]

Code Consistency and Import Order:

• Reordered imports in several files (including bootstrap/app.ts, bootstrap/cli.ts, config/index.ts, and multiple test files) to comply with the new formatting and linting rules. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]

These changes collectively enforce a consistent code style and stricter code quality standards throughout the project.
