The case-insensitive "Not Applicable" fix caught schools where GIAS publishes
statutory ages, but some independent schools leave those blank too — they fall
through every branch and end up with null phase and no pill in the UI.
Add a third tier that infers phase from the school name
(Primary/Infant/Junior/Prep vs Secondary/High/Grammar/Senior/Upper) and also
normalise "Not Applicable" handling with trim() + "unknown"/"" exclusion, so
the final else branch can safely return null instead of the catch-all string.

GIAS provides 'Not Applicable' (capital A) but the check used 'Not applicable',
so the case-sensitive != matched true and skipped the age-range inference.

Independent schools have phase='Not applicable' in GIAS. Now infer
phase from statutory age range: <=11 → Primary, >=11 → Secondary,
spans both → All-through. Falls back to original value if no age data.

- Declare all 34 columns needed by dbt in GIAS tap schema (target-postgres
only persists columns present in the Singer schema message)
- Use nullif() for empty-string-to-integer/date casts in staging models
- Scope daily DAG dbt build to GIAS models only (stg_gias_establishments+
stg_gias_links+) to avoid errors on unloaded sources
- Scope annual EES DAG similarly; remove redundant dbt test steps
- Make dim_school gracefully handle missing int_ofsted_latest table
