Security Enhancements, Depndency Upgrades, Enahncements

Security Enhancements
- Added URL validation for redirects through session.returnTo (CWE-601).
- Fixed OAuth state parameter generation and handling to address CSRF attack vectors in the OAuth workflow.
- Added additional sanitization for user input in database queries using $eq in MongoDB.

API and Integration:
- Unified formatting for authentication parameters in route definitions and passport.js configuration.
- Refactored common code for OAuth 2 token processing in passport strategies to improve maintainability.
- Reworked the GitHub and Twitch API integration examples with additional data from the APIs.
- Reworked the Twilio API integration example to use Twilio’s sandbox servers and test phone numbers.
- Upgraded the Pinterest API example to use v5 calls instead of the broken v1.
- Reworked the Tumblr API integration example with additional data from the API.
- Added a properly working OAuth 1.0a integration for Tumblr.
- Removed sign-in by Snapchat due to increased difficulty for developers and a focus on hackathon participants.
- Removed Foursquare OAuth authorization and updated the API demo with new examples.

Update/Upgrades:
- Migrated from the unmaintained passport-linkedin-oauth2 to a passport-openidconnect strategy.
  o Added support and examples for openid-client.
- Migrated from the deprecated paypal-rest-sdk to an example without the SDK, providing OAuth calls depending on the page state.
- Migrated from the unmaintained bootstrap-social to a fork that can be easily patched and updated.
- Migrated eslint to v9, and its new config format (breaking change).
- Migrated Husky to v9, and its new config format (breaking change). Fixed Windows commit issue.
- Updated dependencies.
- Added temporary patch files for connect-flash and passport-openidconnect based on pending pull requests or issues on GitHub.

Other:
- Fixed a bug that prevented profile pictures from being displayed.
- Added authentication link/unlink options to the user profile page for all OAuth/Identity providers.
- Fixed typos, broken links, and minor formatting alignment issues on various pages.
- Fixed spelling errors in startup information displayed in the console.
- Refactored URL validation in unit tests for Gravatar generation to conform with CodeQL rules. Even though CodeQL does vulnerability checks, this is not a security issue since it is unit tests.
- Updated the placeholder main.js to use the current format (not deprecated JS).
- Updated the GitHub repo worker/runner configs to use proper permissions
- Return exit code 1 if there is a database connection issue at startup.
- Added the --trace-deprecation flag to startup to provide better information on runtime deprecation warnings.
- .gitignore file to exclude the uploads path.
- Updated the copyright year.
- Updated documentation.
