imap: replace atoi() with strtol_i() for UIDVALIDITY and UIDNEXT parsing

Replace unsafe uses of atoi() with strtol_i() to improve error handling
when parsing UIDVALIDITY, UIDNEXT, and APPENDUID in IMAP commands.
Invalid values, such as those with letters, now trigger error messages and
prevent malformed status responses.
I did not add any test for this commit as we do not have any test
for git-imap-send(1) at this point.
