[WhyAsh5114]

Description

Stuff regarding V2 migration work, almost done with V3 now, let's go! Fixes #109.

Type of change

• New feature (non-breaking change which adds functionality)

Tasklist

• migration tRPC implementation
• fix data losses: rest days
• figure out mesocycle start and end dates
• bodyweight exercises not being migrated as bodyweight exercises in MesocylceExerciseTemplate
• add input to take average workout time to improve workout duration assumption
• remove (or at least improve) bodyweight assumption, use input during migration if not available in v2
• or mark user as migrated from v2 to prevent multiple duplicate migrations?

Won't be doing

• allow active mesocycle (should be either on v2 OR v3, NOT on both)
• give option for v2 migration in Getting started component? (maybe)

V2 task

• add v3 banner in v2 with migration guide
