Fix: Timeframe Parameter Consistency on Navigation

[GODrums]

Motivation

Fixes a bug where the timeframe parameters assumed invalid states on browser tab change or same page-navigation, i.e. when clicking on the logo in the header.

Description

This PR is a follow-up to #188 and fixes:

• after/before-param consistency in the URL:
  • when switching tabs
  • when navigating on the same page (e.g. removing query params without changing the page -> revelant for Hephaestus-logo in header) go back to default timeframe (i.e. current week)
• remove state logic from home component and move to timeframe component
• incorrect time ranges in current week ("Custom Range") - now uses the actual end date of the week instead of current minute

Testing Instructions

• Run application-server and webapp
• Navigate through different leaderboards
• Use the Hephaestus-Logo and check if you get navigated back to the default leaderboard
• Go to a different browser tab and back (state should stay the same)
• Leave the leaderboard open for a few minutes and check if the state stays valid after switching timeframes back and worth
