Ruben Fiszel b5a0d46695 fix(auth): filter resource/variable listings by token scope (WIN-1981) (#9302)
A token scoped to a single resource (e.g. `resources:read:u/alice/foo`)
could call `GET /api/w/{w}/resources/list_search` and receive `path` and
`value` for unrelated resources in the workspace. Route-level scope
checks only validate `domain:action`; per-resource handlers do a
`check_scopes` against the path, but the listing endpoints did not —
leaking integration credentials, API keys, and other secrets stored as
resource values to narrowly-scoped tokens.

Add `build_scope_path_predicate` to `windmill-api-auth` (mirrors
`check_scopes` semantics but parses the token's scopes once, suitable
for filtering many rows). Apply it to `list_search_resources`,
`list_resources`, `list_names` (resources) and `list_variables`
(non-secret value leak), so a scope-restricted token only ever sees the
paths it is authorized to read. Unscoped tokens and tokens whose only
scopes are `if_jobs:filter_tags:*` are unaffected.

Includes regression tests covering: unscoped, tag-filter-only,
single-resource, wildcard, wrong-domain, and write-implies-read.

Fixes WIN-1981
