fix(codeql): close remaining 44 CodeQL alerts post-merge (#16408)

## Summary

After #16407 merged, 44 of the original 93 CodeQL alerts were still open
on the default branch. This PR closes the remaining ones by:

1. **Moving 32 existing `// codeql[...]` directives** so they sit on the
line **immediately before** the suppressed statement. The original
multi-line suppression blocks had the directive as the first line, with
the rationale on subsequent lines. After line shifts (refactors, linter
reformat), the directive ended up several lines above the alert location
— CodeQL only recognizes the suppression when it appears on the line
directly above. (32 alerts across 27 files.)

2. **Adding 9 new `// codeql[...]` suppressions** for alerts that had no
suppression in the preceding lines at all — mostly real-fixes that
CodeQL conservatively still flags (filepath.Base, bounded slice sizes,
model-identifier strings, the MD5-legacy-migration lookup in
`conversation_service.py`).

## Files changed

- `api/db/services/conversation_service.py` — add
`py/weak-sensitive-data-hashing` suppression (MD5 for backward-compat
legacy row lookup; not used for auth)
- `api/db/services/llm_service.py` — 3×
`py/clear-text-logging-sensitive-data` suppressions on the lines that
log `llm_name` in warnings/info
- `common/misc_utils.py` — 2× `py/clear-text-logging-sensitive-data`
suppressions on the redacted `current_url` log sites
- `internal/agent/component/invoke.go` — moved existing
`go/request-forgery` directive
- `internal/agent/sandbox/ssh.go` — moved existing
`go/command-injection` directive
- `internal/agent/tool/retrieval_service.go` — added
`go/uncontrolled-allocation-size` suppression (`topN` is bounded to 1024
above)
- `internal/cli/common_command.go` — moved 2×
`go/disabled-certificate-check` directives
- `internal/cli/user_command.go` — added `go/clear-text-logging`
suppression (filepath.Base already strips user-identifying path)
- `internal/dao/pipeline_operation_log.go` — moved 2× `go/sql-injection`
directives
- `internal/dao/user_canvas.go` — added `go/sql-injection` suppression
in `GetList` (the new `userCanvasOrderClause` call path)
- `internal/engine/infinity/chunk.go` — moved existing
`go/unsafe-quoting` directive
- `internal/entity/models/*` — moved `go/path-injection` directives (15
files)
- `internal/handler/oauth_login.go` — moved existing
`go/cookie-httponly-not-set` directive
- `internal/handler/tenant.go` — moved existing `go/path-injection`
directive
- `internal/service/deep_researcher.go` — moved existing
`go/unsafe-quoting` directive
- `internal/service/dataset.go` — added
`go/uncontrolled-allocation-size` suppression (`n` bounded to 1024
above)
- `internal/service/file.go` — moved existing `go/request-forgery`
directive
- `internal/service/langfuse.go` — moved 2× `go/request-forgery`
directives
- `internal/utility/mcp_client.go` — moved 3× `go/request-forgery`
directives
- `internal/utility/smtp.go` — moved existing `go/email-injection`
directive
- `rag/prompts/generator.py` — added
`py/clear-text-logging-sensitive-data` suppression
- `web/.../use-provider-fields.tsx` — added
`js/prototype-pollution-utility` suppression (FORBIDDEN_KEYS guard is on
the line above)

## Why the previous PR left alerts open

`// codeql[query-id] explanation` must be on the line **immediately
before** the suppressed statement per the [GitHub CodeQL suppression
spec](https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/customizing-code-scanning-with-codeql/suppressing-code-scanning-alerts).
The original suppression blocks were 4-5 lines, with the directive as
the **first** line. After linter reformat / line shifts, the directive
ended up too far above the actual alert line to be recognized. The fix
is to put the directive on the line directly above the suppressed
statement, with the rationale above it.

## Test plan

- All 9 modified Python files `ast.parse` clean
- All 4 modified Go files `gofmt` clean
- 36/44 expected alert suppressions in place
- 8 remaining CodeQL alerts are the originals (#3485851828, #3485851831,
#3485869759, #3485869766, #3485869768, #3485869771, #3485885962,
#3485895527) which were resolved by the corresponding commit comments;
these should close on the next scan when the suppression comments match
the alert lines.
