Part of the road to 1.0 (see #33).

SecurityHeaders() (internal/middleware/middleware.go) sets HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy, but no cache directives. Authenticated pages (source list/detail/logs, profile) can therefore be cached by browsers and intermediary proxies, potentially exposing webhook configuration and captured event data.

Definition of done:

authenticated responses carry Cache-Control: no-store (and Pragma: no-cache for older intermediaries)
static assets served under /s are unaffected (they are safe to cache)
a test asserts the header is present on an authenticated page and absent/normal on static assets

Part of the road to 1.0 (see #33). `SecurityHeaders()` (`internal/middleware/middleware.go`) sets HSTS, CSP, `X-Frame-Options`, `X-Content-Type-Options`, `Referrer-Policy`, and `Permissions-Policy`, but no cache directives. Authenticated pages (source list/detail/logs, profile) can therefore be cached by browsers and intermediary proxies, potentially exposing webhook configuration and captured event data. Definition of done: - authenticated responses carry `Cache-Control: no-store` (and `Pragma: no-cache` for older intermediaries) - static assets served under `/s` are unaffected (they are safe to cache) - a test asserts the header is present on an authenticated page and absent/normal on static assets

Implementation instructions

Confine to internal/middleware/middleware.go (plus its test) and internal/server/routes.go only.

Add a NoCache() middleware to middleware.go that sets Cache-Control: no-store and Pragma: no-cache on every response it wraps, following the same constructor style as SecurityHeaders() / MaxBodySize() (returns a func(http.Handler) http.Handler).
Wire s.mw.NoCache() onto the dynamic app route groups in routes.go — the /pages, /user/{username}, /sources, and /source/{sourceID} groups (the same groups that already use CSRF()), placed adjacent to the existing CSRF() call for readability.
Do NOT apply it to the static file mount (/s), /metrics, /webhook/{uuid}, or /.well-known/healthcheck — those are not authenticated pages and static assets are safe to cache.

Definition of done:

authenticated pages (source list/detail/logs, profile, and the login page) carry Cache-Control: no-store
the static /s mount is not given no-store
a middleware unit test asserts NoCache() sets both headers

Gates and process:
