saas: DocumentClassifier + PAYG data model (#6460)

# Description of Changes

Two layers — the `DocumentClassifier` utility plus the full data model
for the new billing engine. Nothing wires the entities into application
behaviour yet; services and controllers land in follow-up PRs.

**Companion PR:**
[Stirling-PDF-SaaS#296](https://github.com/Stirling-Tools/Stirling-PDF-SaaS/pull/296)
— Supabase migration for the v3 dev branch, schema-equivalent to the
Flyway migration in this PR.

## 1. DocumentClassifier (under `payg.docs`)

`DocumentClassifier` computes the doc-unit cost of an uploaded file (or
multi-file input) under a `PricingPolicy`. PDFs read page count via
`stirling.software.jpdfium.PdfDocument`; non-PDFs are bytes-only.
Formula: `max(ceil(pages / docPagesPerUnit), ceil(bytes /
docBytesPerUnit))` clamped to `[1, fileUnitCap]`. Multi-file is the sum
of raw per-file units capped at `fileUnitCap × file_count`.

Two floors, by design: the classifier returns `docUnits` with an
absolute `1` floor for non-empty input; the policy-level
`minChargeUnits` is intentionally applied later, at process-open time in
`JobChargeService`, per design § 3.4 (`unitsForProcess =
max(policy.min_charge_units, docUnits)`). Documented in the interface +
impl javadoc.

Upload bytes are materialised through
`TempFileManager.createManagedTempFile` so jpdfium gets a `Path`; the
temp file auto-deletes on close.

Twelve tests, all in-memory fixtures generated with PDFBox at test time
— no committed binary blobs.

## 2. PAYG data model (under `payg.*`)

JPA entities, repositories, and a Flyway migration covering the full
schema in §6 of the design.

**Enums** (`payg.model`):

`JobSource`, `ProcessType`, `JobStatus`, `JobStepStatus`,
`ArtifactKind`, `LedgerEntryType`, `LedgerBucket`, `ReferenceType`,
`EntitlementState`, `FeatureSet`, `FeatureGate`, `WalletEngine`,
`CapPeriod`, `AutoGroupStrategy`.

**Entities + repositories:**

| Entity | Table | Notes |
|---|---|---|
| `PricingPolicy` | `pricing_policy` | Promoted from a record.
`stepLimits` is `Map<JobSource, Integer>` persisted via normalised child
table `pricing_policy_step_limit`. `stripePriceIds` is `Set<String>`
persisted via `pricing_policy_stripe_price` — currency comes from
`stripe.prices` via Sync Engine, not stored locally. |
| `ProcessingJob` | `processing_job` | UUID PK. Tracks lineage window
via `step_count` and `last_step_at`. |
| `ProcessingJobStep` | `processing_job_step` | Per-tool-call audit. |
| `JobArtifactHash` | `job_artifact_hash` | Composite key `(job_id,
content_hash, kind)`. `content_hash VARCHAR(128)` so multiple signature
schemes coexist as `"type:value"` storage keys. Lineage detector queries
this. |
| `WalletLedgerEntry` | `wallet_ledger` | Append-only, signed
`amount_units`. Two unique indexes kill double-posting. |
| `WalletPolicy` | `wallet_policy` | Per-team engine + cap + degradation
rules + lineage strategy. No `@Version` — admin-only writes (documented
in javadoc). |
| `WalletEntitlementSnapshot` | `wallet_entitlement_snapshot` |
Composite key `(team_id, user_id)`; `user_id = 0` is the team-wide
sentinel. No `@Version` — full-row recompute via
`EntitlementService.recompute` (documented in javadoc). |
| `PaygShadowCharge` | `payg_shadow_charge` | Per-job diff while in
`PAYG_SHADOW` engine mode. |
| `PaygTeamExtensions` | `payg_team_extensions` | Sidecar 1:1 with
`teams` carrying `pricing_policy_id` (per-team override) +
`stripe_customer_id`. Sidecar pattern (mirrors `saas_team_extensions`)
so OSS Hibernate ddl-auto never sees PAYG columns on `teams`. |

**Column adds:**

- `team_memberships.cap_units` (optional per-member sub-cap)

**Width split (intentional, documented in V11):** per-row deltas
(`wallet_ledger.amount_units`, `processing_job.charged_units`) are
`INTEGER` because no single charge realistically approaches 2B units.
Cap and period-rollup columns (`team_memberships.cap_units`,
`wallet_policy.cap_units`,
`wallet_entitlement_snapshot.period_spend_units / period_cap_units`) are
`BIGINT` because they accumulate across a billing period and admins may
legitimately set headroom-cap values into the millions.

**JPA wiring:** `SaasJpaConfig` was updated to include
`stirling.software.saas.payg.repository` in
`@EnableJpaRepositories.basePackages` and `stirling.software.saas.payg`
in `@EntityScan` (covers `payg.policy` / `payg.job` / `payg.wallet` /
`payg.entitlement` / `payg.shadow` recursively). New
`SaasJpaConfigScanTest` reads the annotations reflectively and asserts
every expected package is wired — catches the next time someone adds a
new sub-package without updating the scan paths.

**Migration:** `V11__saas_payg_model.sql` (purely additive).
Schema-equivalent to the Supabase migration in the companion PR —
including the `VARCHAR(128) content_hash` width that's needed for the
multi-signature-scheme storage encoding the lineage layer uses.

## 3. Smoke tests

`PaygEntitiesSmokeTest` exercises each entity via the no-arg ctor JPA
requires, plus getter/setter round-trips and composite-key equality —
catches Lombok/annotation regressions without needing a database.
Real-DB integration coverage lands alongside the services that consume
each entity.

## Why this is safe to land now

- All schema changes are additive — no existing rows modified, no
columns dropped.
- The entities are not yet referenced from any production code path;
they exist for the next PRs to build on.
- The v3 Supabase dev branch picks up the schema via the companion PR;
the main repo's Flyway migration applies the same shape when an instance
boots against a freshly-migrated v3 database.

## Open decisions made

- **Step-limits keyed by `JobSource`** rather than by `ProcessType`.
Captures the "self-hosted gets a different knob" framing in earlier
feedback. Trivially overridable per pricing policy version.
- **Step limits + Stripe price IDs normalised into child tables** rather
than JSONB on `pricing_policy` (per Connor's review on #296). Typed
columns, queryable directly, no JSON parsing.
- **Currency dropped from `pricing_policy_stripe_price`** — it lives on
`stripe.prices.currency` and is resolved via Sync Engine. App is
currency-blind.

## Rollback

Straight `git revert` on this PR. The Supabase migration in #296 is
additive and can be left in place safely — the running app ignores
tables it doesn't reference.
