Linter fixes

[alexandratran]

Description

• Vale was previously misconfigured and not running on any doc files. This PR updates the config to ensure the CI runs on all changed lines in md/mdx files. Reviewdog will report warnings and errors. Vale updated in update docs-spelling-check Consensys/github-actions#119 to reflect latest MetaMask conventions and balance strictness; we can continue to update if Vale introduces too much friction in new PRs.
• Fix most significant/common Vale errors in metamask-connect, smart-accounts-kit, and snaps folders. embedded-wallets may have significant remaining errors.
• Update Prettier CI to only run on changed files. In case contributors bypass the Prettier pre-commit hook and CI for some reason, other PRs won't be blocked by unrelated Prettier issues.
• Fix Prettier issues + ignore generated SAK glossary

Note

Medium Risk
CI behavior changes: Vale now runs across the repo’s doc changes and Prettier only checks changed files, which could alter PR gating and miss formatting issues outside the diff if the change-detection step fails.

Overview
Tightens docs quality checks by updating CI: Prettier now runs only on files changed in the PR (using tj-actions/changed-files), and Vale spelling/style checks are no longer path-scoped (with full git history via fetch-depth: 0).

Applies broad documentation lint fixes to satisfy Vale/Prettier conventions across metamask-connect, smart-accounts-kit, and snaps (terminology shifts like sign-in/sign-out, capitalization such as Wallet Standard/Wallet Adapter, link fixes to .mdx, table/MDX formatting, and selective vale off/on blocks).

Treats the Smart Accounts Kit glossary as generated output by ignoring it in .gitignore/.prettierignore, and simplifies scripts/generate-smart-accounts-glossary.js by removing Prettier formatting and wrapping execution in a synchronous try/catch.
