fix(security): log-injection, http-to-file-access, client-side-request-forgery (#1456)
* fix(security): U11 log-injection, http-to-file-access, client-side-request-forgery

U11.1: Add validateLLMBaseUrl() in llm-client.ts; called at the top of
callLLM() to reject non-http/https schemes and http:// to non-loopback
hosts before any fetch that writes LLM output to disk.

U11.2: Strip CRLF from groupDir in bridge-db.ts openBridgeDbReadOnly
before logging (defence-in-depth on top of pino's JSON escaping).

U11.3: Replace console.log with logger.debug and sanitize normalizedName
/ job.id in api.ts resolveRepo to close js/log-injection alerts.

U11.4: Add validateBackendUrl() in backend-client.ts; called inside
setBackendUrl() to reject non-http/https schemes before the URL is
stored as a fetch target, closing js/client-side-request-forgery alerts.

U11.5: Tests added:
- wiki-llm-client.test.ts: validateLLMBaseUrl happy/error paths
- server-connection.test.ts: validateBackendUrl and setBackendUrl
  rejection paths

All new tests pass (30/30 wiki-llm-client, 18/18 server-connection,
30/30 bridge-db).

* fix: correct IPv6 loopback check in validateLLMBaseUrl

Node's URL parser preserves brackets in hostname for IPv6 addresses
(e.g. http://[::1]:11434 yields hostname '[::1]'), so strip them
before comparing against '::1'. Add a test to cover this case.

* fix: also sanitize error message in bridge-db log call

Sanitize lastErr.message (which may contain a file path from ENOENT
errors) alongside groupDir to prevent CRLF injection from error
message content. Addressed code review feedback.

* fix: address security review findings — credential hygiene and test coverage

[LOW] Redact credentials from URL validation error messages:
- validateLLMBaseUrl: malformed URL no longer echoes raw input;
  scheme error shows protocol only; http-non-loopback error uses
  parsed.origin (scheme+host+port) instead of full URL
- validateBackendUrl: same treatment — no raw input in any error path

[INFO] Add state-preservation test for setBackendUrl:
- Proves _backendUrl is unchanged after a rejected call, covering the
  validation-before-assignment ordering.

[INFO] Expand validateLLMBaseUrl adversarial test coverage:
- LOCALHOST uppercase (case-fold path)
- RFC 1918 / IMDS IPs (10.x, 169.254.x)
- Hostname-spoofing (localhost.evil.com, 127.0.0.1.evil.com, localhost.)
- Non-loopback IPv6 (fe80::1, ::ffff:127.0.0.1)
- ftp:// scheme
- Credential-hygiene assertion (sk-secret not in error message)

* style: prettier autoformat U11 security fix files

Fixes the failing 'quality / format' check on PR #1456 by running 'prettier --write' over the 6 files touched by the security fix. Formatting only — no logic change.
