Refactor schema and slots for improved clarity and organization

- Updated `has_or_had_url` slot to allow a broader range of values by changing its range from `uriorcurie` to `Any`.
- Removed obsolete slots: `house_number`, `html_file`, `html_snapshot_path`, and `http_status_code`.
- Introduced new classes: `CeasingEvent`, `FileLocation`, `FilePath`, `HTMLFile`, `HTTPStatusCode`, `HouseNumber`, `MaximumHumidity`, `MinimumHumidity`, `TargetHumidity`, and `WKT` to better represent various concepts.
- Migrated existing slots to new structures, ensuring alignment with RiC-O naming conventions.
- Added new slots: `ceases_or_ceased_through`, `has_or_had_file_location`, `has_or_had_file_path`, `has_or_had_http_status`, and `is_or_was_observed_by` to capture additional metadata.
- Enhanced descriptions and annotations for clarity and context.

+The following ontologies are locally available in `data/ontology/`. Always verify terms against these specific files. **NO HALLUCINATIONS ALLOWED.**

-## 2. Verification Procedure
+## 2. Verification Procedure (MANDATORY)
 
-Before using a URI in a schema, verify it exists in the local file:
+**You MUST verify every term.** Do not assume a term exists just because it sounds standard.
 
 ```bash
-# General verification
+# 1. Identify the source ontology file
-grep -r "Term" data/ontology/
+ls data/ontology/
 
-# Specific verification (e.g. searching for 'hasPart' in Dublin Core)
+# 2. Grep for the specific term (e.g., 'hasFixity')
-grep "hasPart" data/ontology/dublin_core_elements.rdf
+grep "hasFixity" data/ontology/premis3.owl
+# Result: EMPTY -> Term does not exist! DO NOT USE.
+
+# 3. Grep for the correct term (e.g., 'fixity')
+grep "fixity" data/ontology/premis3.owl
+# Result: <owl:ObjectProperty rdf:about=".../fixity"> -> Term exists. USE THIS.
 ```

-- Renamed from has_address per Rule 39 (RiC-O temporal naming)
-- Multivalued to support multiple address types (headquarters, legal, mailing)
-- Use address_type to distinguish purpose of each address
-- Inlined for data portability (address embedded in parent entity)
-- Temporal validity tracked via Address.temporal_coverage or event links
