feat: enhance phone account settings handling for various manufacturers

[bazl-E]

This pull request brings major improvements to the logic for opening Phone Account Settings on Android devices, making the process far more robust and compatible across a wide range of manufacturers and system configurations.

The update introduces:

Manufacturer- and brand-specific handling

Smarter fallback mechanisms

More flexible intent resolution

Together, these changes ensure users are seamlessly directed to the correct settings screen, regardless of their device brand or OS customization.

As part of one of our primary projects, my team and I have been actively using this package — it has been incredibly helpful and reliable. During our integration, we conducted extensive testing across multiple devices and confirmed full compatibility:

✅ SAMSUNG
✅ GOOGLE PIXEL
✅ MOTOROLA
✅ ONEPLUS
✅ NOTHING
✅ OPPO
✅ VIVO
✅ REALME
✅ iQOO
✅ XIAOMI / REDMI
✅ POCO

This update has been thoroughly validated and works great across all the above models.
