This pull request adds new database indexes to improve the performance of queries involving country code fields in the
members.membertable.homeCountryCodeandcompetitionCountryCodecolumns in themembers.membertable, indexing only non-NULL values to optimize queries filtering on these fields.countrycolumn to support efficient case-insensitive searches, managed via a raw migration since this is not directly representable in the Prisma schema.
