fix(bundler): treat a blank active integration as indeterminate in FR-019 (#3886)

`resolve_install_plan`'s two FR-019 guards are a truthiness test and an
`is None` test:

    if active_integration and required != active_integration:   # clash
    if active_integration is None and not integration_explicit: # indeterminate

An empty string satisfies neither, so it falls through to
`effective_integration = required` and the bundle's pinned integration is
silently adopted — the exact outcome the docstring says the guard prevents
("resolution fails instead of silently adopting the bundle's required
integration").

  active=None        -> BundlerError: ... could not be determined
  active='' (blank)  -> effective_integration='copilot'   <-- silent adopt
  active='claude'    -> BundlerError: ... targets integration 'copilot'

Normalise a blank value to None before the guards, and strip first to
match the writer (`integration_state.clean_integration_key`, which returns
`None` for empty/whitespace and strips otherwise) so a padded value is not
reported as clashing with its own unpadded form.
