⏪️ revert: remove SEQERA_ACCESS_TOKEN alias support

Revert addition of SEQERA_ACCESS_TOKEN as an alias for TOWER_ACCESS_TOKEN.
The code now only supports TOWER_ACCESS_TOKEN as before.

- Remove SEQERA_ACCESS_TOKEN priority logic from TowerClient.getAccessToken()
- Remove SEQERA_ACCESS_TOKEN priority logic from PlatformHelper.getAccessToken()
- Revert error messages to only mention TOWER_ACCESS_TOKEN
- Remove updated docstrings mentioning SEQERA_ACCESS_TOKEN support
