Replace all 57 react-hooks/set-state-in-effect sites with the patterns
React recommends:
- dialog forms reset while rendering when the dialog opens, instead of
in an effect after a frame with stale values;
- forms filled from server data resync during render when a new
response object arrives;
- default selections (server, node, storage, disk, user) are derived
from the user's pick and the current list rather than written back
into state.
This also fixes the migrate dialogs resetting the chosen target when
the guest status refreshed, and the image download dialog resetting
"convert to template" on every render while storages were loading.
Unstable `?? []` / `new Set()` hook dependencies are memoized.
Servers can now be connected with a login and password: the panel
authenticates once, creates its own API token on the node (privsep=0) and
uses it from then on. The token can be revoked from the Proxmox UI, cannot
be used for SSH or web login, and appears in the PVE audit log under its
own name. The password stays stored (encrypted) because ProxmoxClient needs
it for SSH fallbacks such as pvecm delnode.
- add proxmox/token_provisioning.py: token creation with free-name
selection and revoke-on-failure so a failed registration does not leave
an orphaned token whose secret was never persisted
- POST /api/servers accepts auto_create_token
- add POST /api/servers/{id}/provision-token to migrate servers that are
still on password auth
- store api_token_value as EncryptedString; it was kept in plaintext while
the password next to it was already encrypted
- drop the unused ProxmoxServerBase schema, a stale copy of the create
schema whose validator rejected the new auth mode
Node detail pages gain a Graphs tab (CPU, IO delay, memory, load average,
network, swap, root filesystem) built on the existing node rrddata
endpoint. The chart card is extracted from the instance graphs tab so both
views share it, and X axis ticks now switch to dates on multi-day ranges.
