feat(curation desk): forward the roster write routes

[feruzm]

Closes #100. Second of four in the "roster is the single source of truth" chain, after ecency/esync-py#60.

Forwards the three new admin-only desk writes:

gateway	upstream
POST /private-api/curation-desk/roster-list	curation/desk/roster/list
POST /private-api/curation-desk/roster-set	curation/desk/roster/set
POST /private-api/curation-desk/roster-retire	curation/desk/roster/retire

They go through ServeDeskWrite like every other desk write, so the body that leaves here is the validated username plus a key whitelist, and a forged username or code cannot ride along. roster-list has an empty whitelist: nothing the caller sends travels.

The cached GET /private-api/curation-desk/roster is untouched. The private view is a POST precisely because it carries notes, added_by and retired rows, none of which may enter a response with an s-maxage.

rules is the one place this file refuses rather than trims. Everywhere else an unknown or out-of-range read filter is dropped so the backend applies its default; here an admin who sets min_weight: 20000 or a misspelled rule key must get an error, not a success that quietly saved something else. Weights are checked against the same 0..10000 vote range the backend enforces, and note against the same varchar(200).

Verified in a mcr.microsoft.com/dotnet/sdk:10.0 container, since this box has no dotnet SDK: 502 tests pass, 15 of them roster. Removing the unknown-rule check makes one of the new tests fail, and it passes again when restored.

High-Level Assessment

Reusing ServeDeskWrite with declarative route whitelists is the best fit because it preserves existing authentication, no-store behavior, trusted-username injection, and upstream piping. Dedicated roster handlers or forwarding the original body were considered but would duplicate security logic or permit forged and unsupported fields.

1. Valid Unicode notes are rejected ✓ Resolved 🐞 Bug ≡ Correctness

Description

RosterSet applies MaxCuratorNoteLength through .NET string.Length, which counts UTF-16 code
units rather than Unicode characters. A note containing 200 supplementary characters such as emoji
therefore has length 400 and is rejected before reaching the backend's stated 200-character column.

Code

dotnet/EcencyApi/Handlers/PrivateApi.CurationDesk.cs[R1096-1099]

+            if (body.TryGetPropertyValue("note", out var note) && note is not null
+                && body.Str("note") is not { Length: <= MaxCuratorNoteLength })
+            {
+                return "invalid note";

Evidence

The implementation describes the upstream field as varchar(200) but enforces that bound using
UTF-16 length. The only boundary test uses ASCII, for which code-unit and character counts happen to
match, leaving supplementary Unicode affected.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Roster note validation counts UTF-16 code units, causing valid notes containing supplementary Unicode characters to exceed the stated 200-character limit.
## Fix Focus Areas
- dotnet/EcencyApi/Handlers/PrivateApi.CurationDesk.cs[1096-1099]
- dotnet/EcencyApi.Tests/CurationDeskPayloadTests.cs[589-597]
## Recommended Fix
Validate note length by counting Unicode scalar values, such as with `EnumerateRunes().Count()`, rather than using `string.Length`. Add boundary tests using supplementary Unicode characters at and above 200 characters.

2. Roster regressions can pass the suite ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

AllRoutes adds the three roster writes for payload tests, but the shared SignedWrites()
integration enumeration still ends with the older ingest route. Authentication, fail-closed
behavior, token forwarding, client-address isolation, and cache-control tests all iterate that
incomplete enumeration, so defects in the new handler pipeline remain undetected.

Code

dotnet/EcencyApi.Tests/CurationDeskPayloadTests.cs[19]

+        CurationDeskWrites.RosterList, CurationDeskWrites.RosterSet, CurationDeskWrites.RosterRetire,

Evidence

The payload-only route enumeration was extended, while the integration helper contains only the
older writes. Multiple handler-level tests exclusively consume that helper and consequently never
invoke any new roster handler.

dotnet/EcencyApi.Tests/CurationDeskPayloadTests.cs[14-20]
dotnet/EcencyApi.Tests/CurationDeskTestSupport.cs[247-261]
dotnet/EcencyApi.Tests/CurationDeskAuthTests.cs[37-47]
dotnet/EcencyApi.Tests/CurationDeskAuthTests.cs[76-121]
dotnet/EcencyApi.Tests/CurationDeskAuthTests.cs[288-299]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The shared signed-write integration enumeration omits all three newly introduced roster handlers, preventing common handler-pipeline tests from covering them.
## Fix Focus Areas
- dotnet/EcencyApi.Tests/CurationDeskTestSupport.cs[247-261]
## Recommended Fix
Add valid `roster-list`, `roster-set`, and `roster-retire` entries to `SignedWrites()` using their corresponding handlers and request bodies. This automatically includes them in the existing authentication, token, fail-closed, header, and cache-control tests.

All three findings verified against the code and fixed in d076fcf.

Roster writes were missing from SignedWrites() (qodo). Confirmed and the most useful of the three: five shared tests iterate that enumeration (auth, fail-closed, token forwarding, client-address isolation, cache-control) and the three new routes were in none of them. They already behaved correctly, but nothing proved it. Marking roster-retire as ForwardClientAddress: true now fails two tests; before this change it failed none.

note measured in UTF-16 code units (qodo). Confirmed: the column is varchar(200) and the backend counts code points, so 200 emoji measured 400 here and the fence refused notes the column accepts. Counted in runes now, with tests at exactly 200 emoji and at 201.

A present "rules": null skipped validation (CodeRabbit). Confirmed: CopyIfPresent forwards the null through the allowlist while the fence claimed every rules value is an object. Any present rules must now be one. Absent is unchanged, since that is how an admin clears every rule.

504 tests pass. Each fix was mutated until the matching test failed, then restored.
