Tests should stop using hardcoded values

[3esmit]

All tests use hardcoded values to assert:
e.g.:

staking-reward-streamer/test/RewardsStreamerMP.t.sol

Line 937 in 4968ad4

totalMaxMP: 202_465_753_424_657_534_240,

staking-reward-streamer/test/RewardsStreamerMP.t.sol

Line 906 in 4968ad4

totalMaxMP: 200e18,

A function which calculates the the values should be implemented in the tests, and used everywhere.

The test of validity of calculations should be done separated, so hardcoding values only once.

Advantages:

• Clean reading of values
• Stronger assumptions
• Fuzz tests
