Rename com.meesho/org.meesho namespace to com.homelab/org.homelab

Renames src/com/meesho -> src/com/homelab, resources/com/meesho ->
resources/com/homelab, resources/org/meesho -> resources/org/homelab
(via git mv, preserving history), and sweeps every remaining
occurrence of "meesho" (any casing) out of package declarations,
imports, libraryResource() paths, and comments across the whole repo.

Also drops the per-user allowlist in vars/eksCICD.groovy, which
hardcoded real former-colleagues' emails and doesn't apply to a
single-person homelab — that branch is now permanently skipped rather
than deleted outright, to avoid hand-editing the escape-sequence-heavy
echo blocks it guards (eksCICD.groovy itself is unused legacy code,
not called by homelabPipeline.groovy).

Does not touch the ~114 files that were already missing from the
working tree but still tracked in the prior commit — that's unrelated
pre-existing state, left as-is.
