Alex Dunmow 18b7825592 Extract calcomblock into a standalone wasm plugin repo
Convert the bundled backend/internal/plugins/calcomblock package into a
standalone reactor-mode wasm plugin, dropping every git.dev.alexdunmow.com/block/cms
import (forbidden in standalone plugins):

- package calcomblock -> package main; add wasip1 main.go with
  wasmguest.Serve(Registration). go.mod module
  git.dev.alexdunmow.com/block/calcomblock, block/core v0.18.2, no replace
  directives.
- Settings persistence: replace the pool-backed poolQuerier (direct SQL against
  the public-schema `settings` table, which a sandboxed plugin role cannot read)
  with capabilityQuerier over the SDK settings.Settings / settings.Updater
  capabilities. GetSiteTimezone now resolves via GetSiteSettings host-side.
- Vendor the small CMS-internal helpers the plugin used into internal/helpers
  (GetRealIP, StartCleanupLoop, MaskSecret, GetStringOr, the PluginSettingsQuerier
  settings helpers, PluginCrypto for tests) and internal/db (minimal Setting /
  UpsertSettingParams), each with a provenance header.
- Inline the captcha widget: vendor blocks.CaptchaWidget as a local
  CaptchaWidget templ (captcha_widget.templ) and regenerate templ; drop the
  block/cms/blocks import from booking.templ.
- blockConfig (server-authoritative captcha requirement via a
  page_block_snapshots scan) has no wasm-ABI capability, so it is left nil:
  honeypot + per-IP rate limit still apply. Documented as a follow-up.
- web: @block-ninja/ui workspace:* -> ^0.1.0 registry version; eslint.config.js
  repointed at ../../../cms/web/eslint.config.js; rebuild web/dist.
- Rewrite CLAUDE.md for the standalone wasm reality; add .gitignore.

Full test suite preserved and passing; builds to calcomblock-2.0.0.bnp;
check-safety passes.
