May I paraphrase your request: You want file2's sequences to prevail and file1's sequences inserted only if there's no equivalent in file2. If so, try
Code:
tr $'\n>' $' \n' <file1|  grep -vf <(sed -n 's/>//p' file2) | cat  <(tr $'\n>' $' \n' <file2) - |  tr  -s $' \n' $'\n>'

with any length fasta sequences. The traiing ">" can be taken care of piping through | sed '$d' if need be. Please be aware that your desired output's "Contig_98" line is missing an "AG" at the end.
