feat: package manager improvements

[SychO9]

Roadmap item

Changes proposed in this pull request:

• fix global updating and updating issues
• fix false positive major update detection
• fix installation of beta packages (added minimum stability setting) (Fixes #3792)
• improved queue UX by auto refreshing task state and auto reloading the page on a successful operation
• auto clear tasks older than 7 days
• fix some issues with local development environments and added a warning to avoid using the manager when doing local development.
• fix issues with job failure, retires, and unique job runs.
• added queue command failure cause to output modal.
• added soft update and hard update options to extension update (hard update needed when a specific version was used/locked, and when an extension is a requirement of another extension, only soft updates are possible. Also useful when trying to update minor extension versions and not major.)
• allow configuring authentication methods (extiverse)
• allow configuring repositories
• always prefer stable releases
