ci: Joomla release builds ZIP + SHA-256 checksum

Add Step 6b that builds a release ZIP from src/ for waas-component
(Joomla) platforms:
- Zips all files in src/ with root-relative paths
- Computes SHA-256 checksum
- Derives element name from <name> tag (not manifest filename)
- Uploads ZIP as release asset in Step 7

Also fix EXT_ELEMENT derivation in Step 5 (update.xml) to use
<name> tag lowercased instead of manifest filename, so the element
is "mokocassiopeia" not "templateDetails".
