Simplify Convert to take genFileID and drop ConvertedEntry.FileID

Replace the genUUID func() string parameter with genFileID func() littlemoments.FileID,
eliminating the FileIDFromString call inside Convert. Remove the never-read FileID
field from ConvertedEntry. main.go now passes littlemoments.NewFileID directly,
dropping the github.com/google/uuid import.
