docs: how to get testnet $U (public faucet)

[dhernz]

What

Documents how builders get $U on BSC testnet (chain 97), where ERC-8183 job budgets are escrowed in $U.

• sdk/erc8183.mdx — new "Get testnet $U" section: the public faucet's requestTokens() pays 10 $U per address every 30 minutes. Includes the claim from an Altana wallet through the relay (client.execute, the smart account is msg.sender so the payout lands in the wallet) and a cast send one-liner for plain EOAs.
• concepts/networks/testnet.mdx — $U token and faucet addresses added to the testnet address tables, linked to the new section.

Verified

• Faucet parameters read on-chain: tokenAmount = 10e18, waitTime = 1800s, tokenInstance = the $U token (0xc70B…5565).
• requestTokens() simulated successfully via eth_call from a fresh wallet.
• The relay-path snippet mirrors the live testnet hire E2E test, which claimed from this faucet on the real relay.
• Both MDX pages compile with the MDX compiler vocs uses.
