Slim shells across all remaining workflows; drop redundant forge/rm

- flake.nix: re-export .#sol-shell and .#rust-shell (alongside the
  existing .#wasm-shell / .#subgraph-shell) so all workflows can pin
  to flake.lock rainix rev.
- copilot-setup-steps.yml: drop forge install + forge build entirely
  (committed ABIs + vendored IMulticall3.sol mean cargo doesn't need
  them; forge stays available via .#sol-shell on demand). Inline
  raindex-ui-components-prelude body. Use .#wasm-shell.
- npm-package-release.yml: drop forge install + forge build same as
  above. Drop the two rm -rf target/debug guards that pre-dated the
  Swatinem/rust-cache add (free-disk-space@v1 + 8G swap handle the
  budget; the rm was defeating the cache we just added). Switch the
  remaining nix develop -c calls to .#wasm-shell.
- manual-rs-release.yml: .#rust-shell for cargo release (verified
  cargo-release is in rainix rust-shell).
- test-webapp.yaml / test-ui-components.yaml: drop the CARGO_HOME +
  CARGO_TARGET_DIR env redirect (legacy from prep-webapp era). It
  was sending cargo output to .cargo/target/, but
  packages/raindex/scripts/buildPackage.js hardcodes
  ../../target/... for wasm-bindgen — the redirect made
  wasm-bindgen fail to find the .wasm.
