Feat/tbtc faucet amounts

[CharlieC3]

Closes #2187

• Changes the default rBTC faucet amount from 0.5 -> 0.0001 rBTC
• Adds a URL query option to the rBTC faucet to allow the user the request a large amount of rBTC (0.01)
• Adds a URL query option to the rBTC faucet to allow the user the request a xlarge amount of rBTC (the original amount of 0.5)
• Updates some Bitcoin-related text from testnet to regtest since we've replaced Bitcoin testnet with regtest on Stacks testnet

Will fix the btc faucet test in a bit.

If we're concerned about the amount of BTC available, I'd recommend lowering this even further. If we think about in Sats, 0.01 is still a million Sats, so we could go much lower. We'd also want to make sure that our Stacks miners are keeping their spend low, so that other miners can join in with low amounts.

To help out, we could also:

• Add a sink, an easy way for people to send their tBTC back to the faucet
• Make sure that our stackers are sending their tBTC back to the faucet (or directly specifying a faucet address in their stacking commands)

[CharlieC3]

Agreed on lowering the rBTC amount even more in wake of recent discussions, and I like the ideas you mentioned! Those can definitely be ironed out or configured in Q1 2025.
@obycode What default rBTC were you thinking would be suitable if not 0.01? 1k sats?

We may need to go a little higher than 1k because we have to account for what the node considers dust amounts, and will not accept transactions below, which is something like 500-600 sats for a simple transfer. Maybe 10k would be good?

Thank you for this!

If you let me know once 8.4.0 gets deployed to testnet API, I'll update the sBTC bridge code to request less.
I don't even need that, it will just work :)

@aldur This is live! default rBTC faucet requests are transferring 10k sats
