fix(ci): use node:24-slim (glibc) instead of Alpine (musl)

Native modules like @matrix-org/matrix-sdk-crypto-nodejs detect the
libc type at install time and download the appropriate binary.

Previously, CI used node:24-alpine (musl), so native modules downloaded
musl binaries. But production runs on Debian (glibc), causing runtime
crashes when the glibc binary is expected but not found.

This fix:
- Changes CI to node:24-slim (Debian/glibc)
- Adds python3/make/g++ for native module compilation

Fixes: matrix-sdk-crypto-nodejs-linux-x64-gnu MODULE_NOT_FOUND
