- some related interfaces

enhance code readablity.
reduce number of requests by passing the contract info to all chiled functions

- use proxy url in unlockMycontracts
- refactor unlockContracts to accept array of contracts
- add function to unlock contracts by their ids

- add function that takes only contract to unlock it
- add calculate overdue functions

mUSD converter will return the price in mTFT
fix unique name price calc

it is storing the rent contract on a map by the node id, and ignore the unwanted calculations

unlock dialog now will check if the node contract on rented node or not; if so will retrive the rent contract cost and store the and will avoid duplication

…d with selected contracts

…in created state

remove unused import

create constants with numbers repeatedly  used in the calculations
enhance docstring

fix typo

fix name convention

…into development_chain_release2.9

…rting cost per second

skip the node contracts on rented nodes as it already calculated in rent contract

we were ignoring the elapsed seconds for node contracts and we assume that it is the same as rent contract

reorder the calculation logic to be easier in debugging

pass the contracts by id as the contracts do not have the public_ips_number field
