fix: URI encoding for project name

[Luisotee]

This pull request includes changes to the src/routes/auth.js file to ensure that project names are properly decoded before being processed. The most important changes include decoding the project name before checking for existing coordinators and projects, and updating all relevant log messages and comparisons to use the decoded project name.

Improvements to project name handling:

• Decoded the projectName using decodeURIComponent before checking if a coordinator or project already exists.
• Updated the findCoordinatorByProject and projects.find methods to use decodedProjectName instead of projectName.
• Updated log messages to use decodedProjectName instead of projectName for consistency and accuracy. [1] [2]

Additional formatting changes:

• Added spacing between function blocks for better readability. [1] [2]
