Add support for single-quoted multiline values in env loader

👋 TL;DR

Removed unused schema generation code and writeFileSync import from db-pull-dump.ts, and added support for single-quoted multiline values in firebase-env.sh.

🔎 Details

The changes consist of two main parts:

1. Database Script Cleanup: Removed unused writeFileSync import and the entire generateSchemaSql function with its helper getColumnType from db-pull-dump.ts since they were no longer being used. This includes:

   • Schema enumeration and creation logic
   • Table structure generation with column definitions
   • Primary key constraint extraction
   • Index generation
   • Type mapping utilities

2. Shell Script Enhancement: Enhanced firebase-env.sh to properly handle multiline environment variables that use single quotes (') in addition to the existing double quote (") support. The fix adds:

   • Detection of single-quoted values at the start of a line
   • Proper termination when encountering a closing single quote
   • Consistent export behavior for single-quoted multiline values

✅ How to Test

1. Database Script:

   • Verify the script still runs without errors after removing the unused import and functions
   • Confirm the remaining escapeCopyValue function works correctly
   • Run the script to ensure it connects to the database and performs its core functionality

2. Shell Script:

   • Test with environment files containing multiline values using single quotes
   • Test with environment files containing multiline values using double quotes (regression test)
   • Verify that both single and double-quoted values are parsed correctly
   • Test with mixed content to ensure the parsing logic doesn't break existing functionality
