docs(wallets): document Sepolia gas cap after Glamsterdam

[jakehobbs]

Summary

• Adds a "What is the gas cap on Ethereum Sepolia after Glamsterdam?" entry to the Bundler FAQs. It lists the limits from the prod Rundler config (bundles 16,777,216 gas, estimation 16,000,000, verificationGasLimit 10,000,000) and says larger state gas support is planned before mainnet.
• Adds a warning on the Bundler overview (shared bundler.mdx, included on three pages) that links to the FAQ entry.

Test plan

• Not run: pnpm run validate, lint, or a docs build (no node_modules in this worktree)
• Confirm the "working to support larger state gas before mainnet" wording with the Rundler team
• Confirm the FAQ anchor link in the warning resolves

Distinguish execution gas from total transaction gas

For Glamsterdam transactions that use the new state-gas reservoir, 16,777,216 is only the EIP-7825 execution-gas ceiling, not the total transaction gas cap: EIP-8037 permits tx.gas up to 2^32−1 so additional state gas can exceed that boundary. Calling this a transaction gas cap obscures the exact capability that the bundler currently lacks and can lead readers to mistake an Alchemy limitation for a protocol-wide limit; describe it as the execution-gas cap instead.
