[AZ-794] [AZ-795] [AZ-796] Strict input validation + z/x/y rename
AZ-794: rename inventory wire fields tileZoom/tileX/tileY -> z/x/y
to match the slippy-map URL convention. Contract bumped to v2.0.0.

AZ-795: shared validation infrastructure -- FluentValidation +
ValidationEndpointFilter + GlobalValidatorConfig (camelCase paths).
GlobalExceptionHandler now converts JsonException (UnmappedMember +
JsonRequired) into RFC 7807 ValidationProblemDetails. JSON layer
hardened with UnmappedMemberHandling.Disallow + camelCase naming
policy. New error-shape.md contract.

AZ-796: InventoryRequestValidator covers 9 rules (XOR tiles vs
locationHashes, cap 1000, z 0..22, x/y in slippy bounds, hash
length/charset). 16 unit tests + 16 integration tests + a manual
curl probe script.

Adjacent fixes uncovered by the new strict layer:
- IdempotentPostTests RoutePoint payload corrected to lat/lon
  (the DTO has used JsonPropertyName for ages; previously silently
  ignored under PascalCase fallback).
- TileInventoryTests slippy x/y reduced to fit z=18 bounds.
- docker-compose.yml host port for Postgres moved 5432 -> 5433 to
  avoid sibling-project conflict; appsettings.Development + README
  + AGENTS + architecture + containerization docs aligned.

New coderule (suite + repo): API consumer-facing OpenAPI
descriptions must not contain task IDs, contract filenames, or
version-bump history -- internal change tracking belongs in
commits/contract docs/changelogs. Existing offending descriptions
in Program.cs cleaned up.

# Containerization
## Docker Image
**Base image**: `mcr.microsoft.com/dotnet/aspnet:10.0` (was `:8.0` through cycle 3 — bumped by AZ-500)
**Build image**: `mcr.microsoft.com/dotnet/sdk:10.0` (was `:8.0` through cycle 3 — bumped by AZ-500)
**Build strategy**: Multi-stage (restore → build → publish → runtime)
**Exposed ports**: 8080 (HTTP), 8081 (management/metrics)
## Container Composition (docker-compose.yml)
| Service | Image | Ports (host:container) | Purpose |
|---------|-------|------------------------|---------|
| postgres | postgres:16 | 5433:5432 | Database (host port 5433 chosen to avoid conflicts with sibling-project Postgres instances on dev laptops) |
| api | Custom (Dockerfile) | 18980:8080, 18981:8081 | Application |
## Volumes
| Mount | Container Path | Purpose |
|-------|---------------|---------|
| ./tiles | /app/tiles | Tile image storage |
| ./ready | /app/ready | Output artifacts (CSV, summary, stitched, ZIP) |
| ./logs | /app/logs | Serilog file output |
| postgres_data (named) | /var/lib/postgresql/data | Database persistence |
## Health Checks
- **PostgreSQL**: `pg_isready -U postgres` (interval 5s, timeout 5s, retries 5)
- **API**: depends on postgres health (startup ordering)
## Environment Variables
| Variable | Source | Purpose |
|----------|--------|---------|
| ASPNETCORE_ENVIRONMENT | docker-compose | Environment selection |
| ASPNETCORE_URLS | docker-compose | Listen address |
| ConnectionStrings__DefaultConnection | docker-compose | DB connection string |
| MapConfig__ApiKey | Host env `GOOGLE_MAPS_API_KEY` | Google Maps API key |
| AZAION_REVISION | Build arg (CI_COMMIT_SHA) | Git revision tracking |
## Build Labels (OCI)
- `org.opencontainers.image.revision` — Git commit SHA
- `org.opencontainers.image.created` — Build timestamp
- `org.opencontainers.image.source` — Repository URL
