Subject: [PATCH] chore: speedup wasm dev build

Here for wasm dev build I replace the `wasm-pack` which is nice, but behind its defaults it hides lots of useful stuff, and I call `cargo build`, `wasm-bindgen` and `wasm-opt` explicitly. Notably `wasm-pack` does not allow custom cargo profiles (https://github.com/rustwasm/wasm-pack/issues/1111).

I also add the new "opt-dev" cargo profile, which is something in the middle between `release` and `dev` - a balance between rebuild speed and runtime performance. This should save lots of time during day-to-day work.

The production version still uses `wasm-pack` and a more tried solution.

The dev version now requires cargo wasm toolchain, `wasm-bindgen` and `wasm-opt` (from `binaryen` project) installed manually. Previously `wasm-pack` would handle that. The dev docker image was updated accordingly.
