docs: post-#27 follow-up — correctness fixes + Vale prose cleanup

[alexander-sei]

What is the purpose of the change?

Corrects existing documentation. This is a follow-up to the now-merged review in #27 — it resolves a few issues the review surfaced but #27 didn't fully address, and clears the actionable Vale prose-lint findings.

Describe the changes to the documentation

Correctness fixes (89629a8):

• Gas price: propagate the 0.02usei chain-wide minimum (per the Cosmos chain registry's fixed_min_gas_price and docs: fix factual errors, broken examples, and migrate to Hardhat 3 #27's own note) to the node guides and validator tx examples that still showed 0.01usei — node-operators, validators (create-validator + gov vote), seictl, technical-reference. The auto-generated seid init default block is intentionally left untouched.
• ethers v6: receipt.transactionHash → receipt.hash (4 sites in the bank precompile guide), and rename the mislabeled amountInUsei (it parses 18-decimal wei) to amountInWei.
• node-operators DB maintenance: reorder the block so the backup runs before the destructive wipe — previously the cp ran after the wipe, copying an empty data dir.
• Imports: learn/accounts.mdx now imports precompile constants from @sei-js/precompiles (matching every other precompile page) instead of @sei-js/evm.
• Hardhat: evm-hardhat.mdx uses network.create() (the official Hardhat 3 API) instead of network.getOrCreate().

Vale prose cleanup (eeb292a):

• Terminology: "gas fees" → "gas" across 17 pages (22 hits); "Metamask" → "MetaMask".
• Qualifiers: drop filler (really/simply/completely/essentially/very) at 19 sites.
• Sei.Terminology rule: remove the noisy bare-CW → CosmWasm swap. It only fired on legitimate shorthand ("CW pointer", "CW-based", "CW NFT", "CW standards") — CW20/CW721/CW1155 were never matched (the trailing digit blocks the word boundary). CosmWasm casing stays enforced by the [Cc]osmwasm rule.

Notes

• Verified: vale now reports only the pre-existing sentence-case heading backlog (Sei.Headings), left untouched per the CI's advisory, changed-lines-only policy; typos reports 0.
• In-code occurrences of "gas fees" (console.log/throw) and the dev-gas SEO keyword are intentionally preserved.
• Rebased onto current main (clean — no overlap with the llms.txt regeneration).

PR Summary

Low Risk
Documentation and lint-rule changes only; no runtime code. Operators copying updated examples may see different (correct) gas settings and Hardhat/ethers patterns.

Overview
Follow-up to #27: correctness fixes across node/EVM/learn guides plus Vale-driven prose updates.

Correctness: Node and validator docs now use 0.02usei for mainnet minimum gas (with a note on chain-wide enforcement) in app.toml examples, seictl patches, and --gas-prices CLI samples. evm-hardhat.mdx switches Hardhat 3 samples from network.getOrCreate() to network.create(). learn/accounts.mdx imports precompile constants from @sei-js/precompiles instead of @sei-js/evm. The bank precompile guide uses ethers v6 receipt.hash and renames amountInUsei → amountInWei. node-operators.mdx database maintenance now backs up before the destructive wipe.

Prose / lint: Vale Sei.Terminology drops the bare CW → CosmWasm rule (with a comment that CW shorthand is intentional). Widespread “gas fees” → “gas”, MetaMask casing, and trimming filler words (simply, really, etc.) across many MDX pages.
