Fix float formatting to use DatabaseTypeName for bitSize and add connectCommand validation

- Use DatabaseTypeName() to determine bitSize (32 for REAL, 64 for FLOAT) instead of relying on Go type
- Add validation in connectCommand to prevent panic when invoked without parameters
- Fix import grouping in console_redirect.go to follow Go conventions
