Add ACCT to Manufacturers list

[RunnyCow]

Description

This PR is a documentation-only update to the official Betaflight manufacturer ID list (Manufacturers.md). It adds a new manufacturer ID entry for Accton Technology Corporation (ACCT) to support workflows in the Betaflight Configurator.

• Added Entry: ACCT (Accton Technology Corporation)
• Contact URL: https://www.accton-iot.com
• Placement: The new row has been inserted alphabetically between LEGA and AEDR to maintain order and file consistency.
• Impact: No existing manufacturer entries or functional codes were modified or removed.

Contribution Type

• Documentation / Website / Wiki / Translation
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Hardware Compliance & Review Requirements

As this is a pure documentation asset change under the betaflight/config guidelines, full functional hardware validation and flight testing do not apply to this specific pull request.

• Hardware Testing Status: N/A (No target firmware or hardware configuration profiles are introduced)
• Applicable Guidelines: This pull request follows the standard peer-review and data accuracy validation process for Manufacturers.md list additions, rather than the functional hardware certification workflow required for new flight controller targets.

Checklist

• My pull request is from a custom branch, not direct from master
• Tested on hardware (N/A - Documentation only)
• Follows coding style (N/A)
• Updated documentation / manufacturer list
• Verified target compilation (N/A)

Summary by CodeRabbit

• New Features
  • Added support for Accton Technology Corporation as a manufacturer
  • Added G-FF4 flight controller board configuration with STM32F405 processor, motor control, sensor integration (accelerometer, gyro, barometer, magnetometer), and comprehensive I/O mapping

We should wait to merge new manufacturers until they have an approved target under review as well
