Landing page (Paragraphs) Components field does not render when vbp_text_and_image installs before varbase_landing

Problem/Motivation

On Varbase 9.2.x (Drupal ~11.4) the Landing page (Paragraphs) content type's Components field (field_lp_paragraphs) does not render on the node add/edit form. There is no Add Component button, so no paragraphs can be added to a Landing page.

Root cause: vbp_text_and_image and varbase_landing depend on each other. vbp_text_and_image_install() calls vbp_text_and_image__add_target_bundle_text_and_image_to_landing_page_components(), which edits field.field.node.landing_page.field_lp_paragraphs. When vbp_text_and_image is installed before varbase_landing has imported that config, the helper writes a partial config (missing field_type). That invalid config then blocks varbase_landing's optional config import, and the field cannot be loaded (Unable to determine class for field type ''), so the widget is dropped from the form.

Steps to reproduce

1. Install Varbase 9.2.x on Drupal ~11.4 (or a Standard site, then enable varbase_landing).
2. Go to /node/add/landing_page.
3. The Components field and its Add Component button are missing.

Proposed resolution

Guard vbp_text_and_image__add_target_bundle_text_and_image_to_landing_page_components() to only extend an existing, fully defined field config (bail when the config is new or has no field_type), so it never writes a partial config. Add hook_modules_installed() in vbp_text_and_image.module to add the text_and_image target bundle once varbase_landing is installed, covering both install orders.
