bobbanandClaude Sonnet 5 130212baec Add an opt-in insecure-TLS mode for the agent, for self-signed certs
Installing the agent against a Homelab Manager instance with a
self-signed cert failed: curl verifies TLS by default on the install
download, the report-tasks.sh fetch inside install.sh, and every
periodic check-in — not just the outer one-liner, so passing -k to only
that first curl wasn't enough. Mirrors the existing Proxmox/Synology
"insecure" toggle pattern already in this app.

- install.sh and report-tasks.sh accept API_INSECURE=true, adding -k to
  their own curl calls; install.sh persists it into the agent's env
  file so the periodic systemd timer picks it up too.
- The Servers & Tasks page has a new checkbox next to the generated
  install/uninstall commands that adds -k and API_INSECURE=true for
  you, so the outer one-liner (which install.sh's own logic can't
  touch) also skips verification.

Off by default — only for a trusted LAN.

# Installs the Homelab Manager task-reporting agent as a systemd timer.
#
# Usage (must run as root — if not already root, put sudo right after the
# pipe so it applies to bash, not to curl):
# curl -fsSL https://homelab.example.lan/agent/linux/install.sh | \
# sudo API_URL=https://homelab.example.lan API_TOKEN=hlm_xxx bash
#
# If Homelab Manager is served with a self-signed certificate, also pass
# API_INSECURE=true (skips TLS verification for every request this agent
# makes — only do this on a trusted LAN) AND add -k to the outer curl
# above, since that first fetch of this very script also hits the
# self-signed endpoint before any of this script's logic can run:
# curl -fsSL -k https://homelab.example.lan/agent/linux/install.sh | \
# sudo API_URL=https://homelab.example.lan API_TOKEN=hlm_xxx API_INSECURE=true bash
