Update finalize dialog text based on READ_AND_CONFIRM flag

The confirmation dialog when finalizing a document now displays
context-appropriate text depending on the READ_AND_CONFIRM flag.
If true, it shows localized.confirmAgree; otherwise, it shows
localized.sigAgree, improving clarity for different workflows.
