feat(i18n): Add Finnish translation preservation to rebrand script

Store all 44 Finnish translation files in custom-logo/translations/ and update bin/rebrand to restore them after upstream merges. Ensures Finnish translations persist across future git pulls from Chatwoot upstream.

+# bin/rebrand — applies LeadChat branding on top of upstream Chatwoot source.
+# Re-runnable after every `git merge upstream/*` to restore the brand.
+#
+# What it does:
+#   1. Copies logo files from custom-logo/ to their target locations
+#   2. Copies favicons and manifest.json from custom-logo/favicons/ to public/
+#   3. Replaces Chatwoot brand colors (#1f93ff / #2781F6) with LeadChat teal (#01a0a5)
+#   4. Updates installation_config.yml defaults (name + URLs)
