* feat(fleet): export a whole-fleet Markdown dossier
Add an admin-only "Export Dossier" action to the Fleet view that walks
every node and stack, pairs each stack's generated Compose anatomy with
its operator notes, and downloads a folder-structured homelab-dossier.zip
(index, per-node and per-stack pages, plus fleet-wide port, volume,
network, env, access-URL, and VLAN/firewall maps).
Reuses the existing stack dossier and anatomy Markdown generators by
extracting the shared Compose parsers into a frontend lib module.
Unreachable nodes are recorded with a reason and never block the export;
only env variable names and counts are ever emitted, never values.
* fix(fleet): unique stack slugs and reproducible dossier archive
Disambiguate stack names on one node that slugify to the same value (e.g.
`Web` and `web` on a case-sensitive host) with a per-node slug map shared by
the node-page links and the file emission, so neither overwrites the other.
Pin a fixed entry timestamp on the zip so the archive bytes are a pure
function of the file map rather than the wall clock.
* feat(stacks): add Stack Dossier tab with operator notes and Markdown export
Add a Dossier tab beside Anatomy and Activity on the stack detail panel. It
shows a read-only summary auto-derived from the stack's Compose anatomy
(services, ports, volumes, network, restart policy, env file, source) plus an
editable form for the context Sencho cannot infer: purpose, owner, access URLs,
static IP, VLAN, and firewall, reverse-proxy, backup, upgrade, recovery, and
custom notes.
Notes persist per stack and per node in a new stack_dossiers table, reached
transparently through the remote-node proxy so a remote stack's dossier
round-trips to the node that owns it. Reading a dossier needs stack read
permission; saving needs stack edit. The tab exports a single Markdown document
combining the generated facts and the operator notes, with copy-to-clipboard and
download actions; env values are never exported, only variable names and counts.
Available on all tiers. The standalone anatomy copy-as-Markdown shortcut is
removed since the Dossier export supersedes it.
* fix(stacks): gate dossier reads/writes on stack existence; clear dossier on node delete
A dossier endpoint validated the stack name but not that the stack exists, so an
editor could PUT a dossier for a name with no stack, leaving an orphan row that a
later stack of the same name would inherit. Require the stack to exist (existing
requireStackExists guard) on the dossier GET and PUT, returning 404 otherwise.
Also clear a node's stack_dossiers rows when the node is deleted, alongside the
other node-scoped cleanup, so removing a node leaves no orphan dossiers.
Docs: scope the "no secret exported" statement to the generated facts (which only
ever carry variable names and counts) and clarify that operator notes are
exported exactly as written.
