refactor(configs): migrate management interface to Management0

This commit updates the management interface configuration across all leaf and spine switches to align with the target environment requirements.

Changes include:
- Changing the primary management interface from `Management1` to `Management0`.
- Removing the `vrf mgmt` assignment, moving the interface to the default global routing table.
- Explicitly configuring `lldp management-address Management0` to ensure the correct management IP is advertised to neighbors.
