Refactor getusedcoinstagstxhashes to use GetSpendsMobile (#1773)

* Refactor getusedcoinstagstxhashes to use GetSpendsMobile for tag retrieval

Updated the getusedcoinstagstxhashes function to replace the use of GetSpends with GetSpendsMobile, changing the data structure from an unordered_map to a vector of pairs for improved performance and compatibility.

* Enforce mobile mode requirement in getusedcoinstagstxhashes

Added a check in the getusedcoinstagstxhashes function to ensure that the application is run with the -mobile flag. If the flag is not set, an error is thrown prompting the user to rerun with the appropriate argument.
