[AZ-500] .NET 8 -> .NET 10 migration

Coordinated cross-cutting bump: 9 csproj TFMs net8.0 -> net10.0;
global.json sdk.version 8.0.0 -> 10.0.0; all Dockerfiles + scripts/
+ .woodpecker on mcr.microsoft.com/dotnet/{sdk,aspnet,runtime}:10.0;
all Microsoft.AspNetCore.* (8.0.25) and Microsoft.Extensions.* (9.0.10)
packages -> 10.0.7. Serilog.AspNetCore retained at 8.0.3 (10.0.0
requires Serilog.Sinks.File >= 7.0.0; out of AZ-500 scope per "no
unrelated package bumps") -- documented in AGENTS.md. Swashbuckle
9.x bumped to 10.1.7 to track Microsoft.OpenApi 2.x; Program.cs +
ParameterDescriptionFilter.cs refactored for the 2.x namespace
(Microsoft.OpenApi), OpenApiSecuritySchemeReference, JsonSchemaType
enum, and IOpenApiSchema dictionary properties. Fixed implicit AC-5
prereq: scripts/run-performance-tests.sh PERF_DLL path bin/Release/
net8.0 -> net10.0. Docs sync: architecture.md + AGENTS.md.

ACs verified: AC-1..AC-4 + AC-7 + AC-8 by grep + build; AC-6 by
./scripts/run-tests.sh --full (271/271 unit tests + full integration
suite green); AC-5 short bootstrap-smoke (PERF_REPEAT_COUNT=2
PERF_UAV_BATCH_SIZE=2) succeeded at the bootstrap step (no exit 3),
PT-01..PT-07 PASS. PT-08 surfaced a pre-existing grep-pipefail bug
in run-performance-tests.sh:417 -- not an SDK problem; recorded as
follow-up in the perf-cycle3 leftover. Code review verdict:
PASS_WITH_WARNINGS (2 Medium deferred per scope discipline:
WithOpenApi ASPDEPR002 deprecation x8, CS8604 nullable in
ParameterDescriptionFilter.cs; both targeted at follow-up PBIs).
