fix: balance calculations to be compatible with new chain changes

[0oM4R]

Description

To get the total balance now we have to add the free and the reserved, locked balance is not used anymore

Changes

• replaced locked with reserved
• show the sum of reserved and free in profile manager
• make freeBalance variable computed to make it always synced with the balanc

Related Issues

• [Qanet] Ensure compatibility with TFChain 2.9 release #3340

Tested Scenarios

• having zero tft, and check the profile manager

• use polkadot UI and call system/account to retrieve the actual balance and compare it with the shown in profile manager

• try to empty you account from balance at all and check for the shown values

• also try to deploy when you have balance less than 2 TFT < should fail>

• try to deploy when the free balance is larger than 2 TFT

Checklist

• Tests included
• Build pass
• Documentation
• Code format and docstrings
• Screenshots/Video attached (needed for UI changes)

works when balance is exactly 2tft

works when balance is exactly 2tft

this is the expected behavior right ?

[amiraabouhadid]

however, rounding the numbers (1.998 is rounded to 2) is confusing in the err msg . I suggest you use the same number of decimals in err msg as used in balance display
