In CCCadmin pilot for multi account creation, unable to upload csv data file with more than 500 rows

Hi,

In the CCC admin pilot at https://admin.pilot.ccctechcenter.org/admin/openccc/bulkcreate, I was trying bulk create the CCCID's for the students using the multi account creation option and I saw the following issues.

1) The file had over 8k records with file size 1355 KB, the file upload failed as it was over 1 MB which is limitation as these 8k records came from a test DB, for PROD DB there will be more records.

2) Even when I reduced the number of records to bring the file size below 1 MB, the page kept on crashing and opening a new instance.

3) I am able to upload a file with 500 records (rows) in it and get results back. More than 500 records the application crashes and opens a new instance.

4) One of the error 'ERROR:invalid.number.for.country field:phone.number' when the CCCID creation fails seems to be generic which gets displayed even with the valid phone number not letting the developer know which part of the data caused it to fail. here are couple examples
