feat(platform): Schedule specific agent version

[kcze]

Scheduling always takes the newest version of an agent.

Changes 🏗️

This PR allows to schedule any graph version by adding number input to schedule popup. Number is automatically set to the newest version when agent is chosen.

• Update API, so it accepts graph version
• Update schedule pop up, so it lets user input version number
• Open and schedule correct agent
• Add Version column to the schedules table

• I have tested my changes according to the test plan:
  • Can schedule version between 1 and max version
  • Reject incorrect version
  • Table shows proper version

Should we just append the version here? e.g: {graph_id}#V{graph_version} instead of a new column ?
