[larm-odoo]

Original Recruitment doc too long, breaking off the recruitment flow section into its own doc.

Task Card for this PR.

Hi @Felicious - this is ready for a first-round review!

Hi @Felicious - now that all the other recruitment docs have been added, this is ready for another look! There were a lot of build errors I had to fix to catch this up to the latest version. I think it's in good shape, but as always- your feedback is amazing- so if you have a chance, I'd love another review.
