🧹 Centralize backend logging

[davidraehles]

🎯 What: Replaced direct console.log and console.error usage in the backend with a centralized logger utility in backend/src/utils/logger.ts.
💡 Why: This improves maintainability by providing a single point of control for logging, making it easier to swap or configure logging libraries in the future.
✅ Verification:

• Created backend/src/utils/logger.ts and verified its content.
• Replaced all direct console. calls in notes.ts, auth.ts, and server.ts.
• Verified replacements with grep.
• Confirmed logger.ts compiles with tsc.
• Ran pnpm run build in backend/ (after generating Prisma client).
  ✨ Result: Backend logging is now standardized and easier to manage.

Additionally, the PR introduces a pnpm-lock.yaml file, suggesting a migration from npm to pnpm as the package manager.

Changes:

• Created centralized logger utility in backend/src/utils/logger.ts with info, error, warn, and debug methods
• Replaced direct console calls with logger utility imports across backend routes and server
• Added pnpm-lock.yaml lockfile to the backend directory

This PR introduces pnpm-lock.yaml alongside the existing package-lock.json file. Having both lockfiles can lead to inconsistencies and confusion about which package manager should be used. The repository should standardize on either npm or pnpm.

If migrating to pnpm:

• Remove package-lock.json from backend/ and frontend/
• Add .npmrc with shamefully-hoist=true or similar pnpm configuration if needed
• Document the change in the project README
• Update CI/CD pipelines to use pnpm

If staying with npm:

• Remove this pnpm-lock.yaml file
• Continue using package-lock.json

Note: The PR description mentions running "pnpm run build" which suggests pnpm is intended, but the existing package-lock.json files indicate the project was using npm previously.

[davidraehles]

Removed pnpm-lock.yaml from the branch.

[google-labs-jules]

Removed backend/pnpm-lock.yaml as requested.

The logger functions use any[] for the rest parameter which bypasses TypeScript's type safety. Consider using unknown[] instead to maintain type safety while still allowing flexibility. This prevents potential issues where incorrect types are passed to the logger.

Example:

export const info = (message: string, ...args: unknown[]) => {
  console.log(message, ...args);
};

This is a minor improvement that would make the logger more type-safe while maintaining the same functionality.

	export const info = (message: string, ...args: any[]) => {
	console.log(message, ...args);
	};
	export const error = (message: string, ...args: any[]) => {
	console.error(message, ...args);
	};
	export const warn = (message: string, ...args: any[]) => {
	console.warn(message, ...args);
	};
	export const debug = (message: string, ...args: any[]) => {
	export const info = (message: string, ...args: unknown[]) => {
	console.log(message, ...args);
	};
	export const error = (message: string, ...args: unknown[]) => {
	console.error(message, ...args);

	export const warn = (message: string, ...args: unknown[]) => {
	console.warn(message, ...args);
