refactor(manifest): the flow pages are an index and a flow

[rubenvdlinde]

Moves this app's flow pages off the two deprecated page types. Part of the fleet-wide sweep that
removes the last custom/aliased flow surfaces (openregister#2937, dossiq#1402, integriq#1622).

Page	Before	After
Flows	type: "flows"	type: "index" + config.entitySource: "flows"
FlowDetail	type: "flow-detail"	type: "flow"

Why

flows predates named index sources. A flow lives in OpenRegister's native flow table rather than a
register/schema pair, so an object-backed index had nothing to bind to and a flow list needed a page
type of its own. config.entitySource closes that gap: the index names the collection and loads it.
So the list is now an ordinary index, and only the editor still needs a type of its own — now
called flow rather than flow-detail.

Both old names still resolve as deprecated aliases, so this is not a fix for a broken page. It moves
the manifest onto the names that are not deprecated, and it is what lets those aliases eventually be
removed.

The _note is updated in the same commit

The list page's note asserted the old rationale — that a flow "cannot be addressed" by an index, or
that this had to be a custom page. This change disproves it. A note that survives the change it
describes is worse than no note: it is documentation that actively argues against the current code.

config.app is untouched

Deliberately. It is not a label — the editor stamps it onto a flow created there, and the index
filters on it. Verified before pushing that it is byte-identical to development.

Verification

Every app in this sweep was checked mechanically before push:

• the text edit was compared against the same change applied structurally, and the two had to
  agree exactly — this caught two real bugs in the first attempt, where the naive edit matched a
  different page's config line
• the result validates against the v2 manifest schema (2.26.0) with jsonschema
• config.app unchanged, page count unchanged, no CnFlowsPage reference left in the note
• no test in any of the 13 apps pins these page types (checked across all tests/**/*.{ts,js})

Blocked on

• @conduction/nextcloud-vue 2.21 — 2.20 declares a named source's columns and create button but
  does not read them (nextcloud-vue#810, #818). The dependency bump follows the release.
• ConductionNL/.github#602 — hydra-gates validates against its own vendored schema copy, still at
  2.25.0, which has neither flow nor entitySource.

CI intentionally cancelled — this is not a failure, and not a verdict.

This PR cannot merge until @conduction/nextcloud-vue 2.21 is published: 2.20 declares a named
source's columns, addLabel and rowActions without reading them, so on 2.20 this page renders a
columnless table with no working create button.

Its queued jobs were competing for org runners with nextcloud-vue#818 and #812 — the release that
unblocks it — which had sat with zero runners for three hours. Cancelling here is what lets that
release through.

Before merging: bump the dependency to ^2.21, then re-run CI. Do not read the cancelled run as
a pass or a fail — a cancelled check is neither, and there is no verdict on this commit yet.
