#1278 add separate functions to delete ARs, merge consecutive ARs

[gabrielwol]

What this pull request accomplishes:

3 new functions:

• delete auto ARs for one day
• merge consecutive/overlapping ARs
• perform delete + add + merge functions in sequence

Issue(s) this solves:

• Closes Clear automated anomalous_ranges during pull #1278

What, in particular, needs to reviewed:

What needs to be done by a sysadmin after this PR is merged

E.g.: these tables need to be migrated/created in the production schema.

Test:

DROP TABLE IF EXISTS gwolofs.anomalous_range_copy_20251106;

CREATE TABLE gwolofs.anomalous_range_copy_20251106 AS SELECT intersection_uid, classification_uid, notes, investigation_level, problem_level, range_start, range_end, leg FROM miovision_api.anomalous_ranges;

SELECT miovision_api.identify_anomalous_ranges('2025-11-01'::date);

--check results are the same:
SELECT intersection_uid, classification_uid, notes, investigation_level, problem_level, range_start, range_end, leg FROM miovision_api.anomalous_ranges
EXCEPT
SELECT intersection_uid, classification_uid, notes, investigation_level, problem_level, range_start, range_end, leg FROM gwolofs.anomalous_range_copy_20251106;

--also test with some intersections that have outages;

        AND ar.range_end = '2025-11-01'::date + 1
