Migrate multiple slots to enhance semantic clarity and align with best practices

- Migrated catering_type to CateringType with subclasses for better classification.
- Updated certainty_level to has_or_had_level for improved metadata consistency.
- Addressed cessation_observed_in by confirming existing temporal data structure.
- Created NetAsset class and updated financial statements for richer financial modeling.
- Completed migrations for default_access_policy, default_audio_language, and default_language to structured classes.
- Migrated default_position to structured Alignment class for better representation.
- Updated defined_by_standard to broaden range for identifier standards.
- Migrated definition to structured Resolution class for video resolution modeling.
- Completed migrations for degree_name, deliverable, and departement_code to structured classes.
- Migrated deployment_date to structured DeploymentEvent with temporal extent.
- Migrated derived_from_entity and derived_from_observation to new reference structures.
- Completed description and description_text migrations to enhance content modeling.
- Migrated detection_count, detection_level, and detection_threshold to structured slots with classes.
- Migrated device-related slots to structured classes for better identification and classification.
- Added new slots and classes for historic building and web address modeling.

+      Event representing the deployment of a software system (CMS, platform) at an institution.
+      
+      **Purpose**:
+      DeploymentEvent captures the full context of a software deployment:
+      - WHEN: Via temporal_extent (TimeSpan with fuzzy boundaries)
+      - WHERE: Via refers_to_custodian (target institution)
+      - WHAT: Linked from CollectionManagementSystem.is_or_was_deployed_at
+      - WHY: Via description (deployment rationale, notes)
+      
+      **MIGRATED FROM**: `deployment_date` slot
+      
+      Replaces simple date with structured event that:
+      - Supports fuzzy temporal bounds (TimeSpan)
+      - Tracks deployment at specific custodians
+      - Enables multiple deployment events per system
+      - Captures deployment context and rationale
+      
+      **Ontological Alignment**:
+      - **Primary**: `prov:Activity` - PROV-O activity
+      - **Close**: `crm:E5_Event` - CIDOC-CRM event
+      - **Related**: `schema:Action` - Schema.org action

+      Abstract base class for reconstructed formal entities derived from observations.
+      
+      **Purpose**:
+      EntityReconstruction represents the result of analyzing multiple observations
+      to reconstruct a formal entity (legal status, name, place).
+      
+      **Relationship to Observations**:
+      ```
+      CustodianObservation[]
+          │
+          └── refers_or_referred_to → EntityReconstruction
+                                          │
+                                          └── (subtypes: CustodianLegalStatus, 
+                                                         CustodianName, 
+                                                         CustodianPlace)
+      ```
+      
+      **PROV-O Semantics**:
+      - `prov:Entity`: Base class for things with provenance
+      - Links TO observations via inverse (has_derived_observation)
+      - Links FROM observations via refers_or_referred_to
+      
+      **Subtypes**:
+      - CustodianLegalStatus - Reconstructed legal entity
+      - CustodianName - Reconstructed emic/etic name
+      - CustodianPlace - Reconstructed place designation

+      
+      **Pattern**: Simple string model name replaced with structured class:

+      Abstract base class for observational evidence from sources.
+      
+      **Purpose**:
+      Observation is the base class for source-based evidence about entities.
+      Concrete implementations include:
+      - CustodianObservation - Evidence about heritage custodians
+      - PersonObservation - Evidence about people (staff, directors)
+      - WebObservation - Evidence from web scraping
+      
+      **PiCo Model Alignment**:
+      Following the Persons in Context (PiCo) model, observations are
+      discrete pieces of evidence from specific sources that may be
+      combined to reconstruct formal entities.
+      
+      **PROV-O Semantics**:
+      - `prov:Entity`: Observations are things with provenance
+      - `is_or_was_based_on`: Links derived entities back to observations
+      
+      **Relationship to EntityReconstruction**:
+      ```
+      Observation[] (source evidence)
+          │
+          └── is_or_was_based_on ← EntityReconstruction
+                                    (reconstructed formal entity)

+      
+      **Use Cases**:
+      - Default language status (is_default: true)
+      - Processing status
+      - Availability status
+      - Publication status
+      
+      **Migration Note**:
+      Created per slot_fixes.yaml revision for default_audio_language
+      and default_language migrations.

+      
+      **Temporal Semantics** (RiC-O Pattern):
+      The "filtersOrFiltered" naming follows RiC-O convention indicating this relationship
+      may be historical - filter settings may change over time affecting detected entities.
+      
+      **Ontological Alignment**:
+      - **Primary** (`slot_uri`): `dqv:computedOn` - DQV predicate for quality metrics
+        computed on a specific dataset
+      - **Related**: `prov:wasGeneratedBy` - provenance of filtered results
+      
+      **Usage**:
+      For annotation classes with detection thresholds and counts, this links the
+      analysis context to DetectedEntity instances that passed filtering criteria.
+      
+      **Pattern**:
+      ```
+      VideoAnnotation
+        └── filters_or_filtered → DetectedEntity
+              ├── has_or_had_quantity → Quantity (detection_count)
