Improvements

[dorianim]

Some ideas to further improve the timer after the German national youth competition in Bexbach.

• Remove seconds in clock
• Start time input has no seconds on IOS (maybe this solution)
• Change time input to separate fields for hours:minutes:seconds
• Changes to pre_start_behaviour:
  • make it a dropdown instead of a tick (Feat: fully support start on demand #27)
  • remove ShowZero (Chore: capsulate redis operations into respository module #26)
  • add ShowFirstInterval (Chore: capsulate redis operations into respository module #26)
  • add ShowLastInterval (Fully support "start on demand" #23)
• Separate configuration and control -> /manage/<timerid> should not have any configuration. Only show the current timer and the buttons restart, pause/resume and "configure"
• Add option to count up (per segment)
• Change from duration and count_to to from and to => this will also allow counting up, but will be a breaking change 🚧
• Refactor calculateNewStartAt and properly define the behavior on changes
• Add option to skip current segment
• Add option for "start signal" that runs when the timer is started (Fully support "start on demand" #23)
• Add template for Worldcup Quali (5min+15s)
• Add an id to the websocket get time command which will be set by the client and sent back by the server
• make frontend controls configurable
  • for the 4min + wait, it should be easier to understand what button does what
• hide time options behind advanced setting to make it easier to configure
• add verifier which shows something like "compliant for ifsc final"
• add option to override color with get parameter (maybe use bgcolor and fgcolor to make @baycom happy... https://github.com/baycom/nodeclock/blob/b279e096f4e6fd774f715199bbec4398708f9c0b/public/js/timer.js#L481C2-L481C9)
• fix high cpu usage
• when a sound is playing and the start_at time changes, the sound should be stopped
