Some providers (notably SiliconFlow) return "network connection error" in the response body when their backend is overloaded or the upstream model connection is disrupted. classifyError() had no pattern for this string, so it fell through to UNKNOWN (non-retryable), surfacing the raw error to the user on the first failure instead of running the exponential-backoff recovery. Adds the pattern to the SERVER_ERROR classifier and a friendly message mapping in extractUserFriendlyError(); bumps MAX_RETRIES from 5 to 10 so sustained wiki batch load can ride out provider flaps without surfacing an error to the channel user.

Model identifiers like 'Qwen/Qwen3-Embedding-8B' or
'Pro/deepseek-ai/DeepSeek-V3' carry forward slashes that Spring MVC
decodes from %2F before path matching, so even with the frontend's
encodeURIComponent the request never reaches the handler and 404s out.
The two affected endpoints take modelId as a request param instead:
DELETE /{providerId}/models/{modelId} -> DELETE /{providerId}/models?modelId=...
POST /{providerId}/models/{modelId}/test -> POST /{providerId}/models/test?modelId=...
modelApi.removeProviderModel / testModel in the UI follow suit, passing
the id via axios params so axios handles the URL encoding consistently.
providerId stays as a path variable — provider ids are kebab-case and
never contain slashes.
Closes#175
ModelConfigController.testEmbedding() previously caught and stringified
the exception's getMessage() into the response body without writing
anything to the server log. Operators investigating an Embedding test
failure saw only the truncated client-side message — root causes like
the DashScope-native vs OpenAI-compat routing bug (#166) or the
requireApiKey gap (#167) were invisible server-side.
Add @Slf4j to the controller and log.error the full stack trace
alongside the failing modelId, so future Embedding test regressions are
diagnosable from the server log without redeploying with debug
breakpoints.
Closes#169
ModelConfigService.validateModel() flagged a duplicate when re-adding a
manually-typed (provider, modelName) pair that happened to match a row
with deleted=1 in mate_model_config. The user-visible symptom: adding
'dashscope/qwen3-plus' fails with 'model identifier already exists',
yet the management page shows no such model.
The project itself runs hard-delete via deleteById(), so the user-facing
delete path doesn't create deleted=1 rows. The stale rows come from
schema migrations (V44, V81) that intentionally tombstone bogus catalog
entries — for instance V81 sets deleted=1 on the non-existent
'qwen3-plus' (id=1000000172) so it stays out of routing but preserves
the id for audit. ModelConfigEntity has no @TableLogic, and the project
has no global logic-delete-field config, so LambdaQueryWrapper queries
do not auto-append the deleted filter; the migration tombstones leak
into the validate-model query.
Add an explicit .eq(getDeleted, 0) to the uniqueness check so migration
tombstones don't block legitimate re-adds.
Follow-up: several other queries in ModelConfigService share the same
oversight (list/get methods), and a future migration could drop the
tombstones entirely to align with the V20 hard-delete posture.
