Outdated term "Subscription" in the Terms of Service

[Stanislaw-bnk]

@gosiastyba Currently, the Terms of Service use outdated terminology with the word "Subscription." The ToS needs to be aligned with the merged document's naming convention: https://docs.dasharo.com/dasharo-naming-convention/

This adjustment will create a clear distinction between PRO and ENTERPRISE in the ToS, specyfying that the ENTERPRISE is for personal use above 5 units but ALSO for companies from the first unit.
