Remove redundant TC acknowledgement requirement flag

[swan-amazon]

Background

Currently, there's a boolean flag in the commissioning flow that controls whether TC (Terms & Conditions) acknowledgement is required. This flag is redundant because:

• TC acceptance is now a mandatory pre-condition for commissioning
• The delayed TC acceptance flow has been removed from the system
• The flag no longer serves any functional purpose

Proposed Changes

• Remove the boolean flag that controls TC acknowledgement requirement
• Keep the actual TC acknowledgement state tracking (this remains necessary)
• Update related documentation and tests

Technical Notes

• This is a cleanup task with no functional changes
• The original flag was implemented to support a now-removed feature where users could provide TC acceptance after starting the commissioning process
• Since TC acceptance is now required upfront, this additional control flag is unnecessary

Impact

• No user-facing changes
• Code simplification
• Reduced maintenance overhead
