Should I really use STA-BIL 360 Marine before every fill-up? Is it truly necessary?

To be blunt, yes, especially if you want to protect your investment. Boats live in a high-moisture environment. STA-BIL 360 Marine is engineered to protect your tank from corrosion and optimize the fuel in the process.

If the color of the liquid in the bottle is no longer blue, is it still safe to use?

Yes. It is possible for the dye in the formula to fade, but it is still perfectly functional.

What happens if I add too much fuel additive to my tank? Will it harm the engine?

No. Overpouring will not cause significant damage to your fuel tank. However, it’s best practice to avoid making this a habit. Miscalculating by an ounce here or there, so long as it is not over four total ounces, is acceptable.
