Remove order attribute on form table

[AidanLoran]

Description

Order attribute for form table is not needed, can instead order by startDate, endDate, etc. based on the specific scenario. This will remove the need to do upkeep on the order attribute as well as any errors that may cause.

TODO

• DB change
• refactor code to accomodate
  • handlers + schemas not requiring/using order
  • composables/pages order logic replaced with scenario-specific ordering
