docs: explain how to find the config entry_id

Added a dedicated 'Finding Your Entry ID' section to actions.md
explaining the two workflows: dropdown in the Action UI vs.
'Copy Config Entry ID' from the integration's three-dot menu in YAML.

Added matching :::info callouts to chart-examples.md and
automation-examples.md where entry_id: YOUR_ENTRY_ID appears in code
examples, and a new 'Config Entry ID' entry in the glossary.

Addresses user confusion reported in GitHub Discussions #94.

Impact: Users no longer get stuck on YOUR_ENTRY_ID placeholders.
Both GUI and YAML workflows are clearly explained at the point of need.

 You can still call them from automations, scripts, and dashboards the same way as before (`service: tibber_prices.get_chartdata`, etc.), just remember that the frontend officially lists them as actions.
 
+## Finding Your Entry ID
+
+Every action requires an `entry_id` parameter that tells Home Assistant which Tibber home (integration instance) to use. If you only have one home, there is still exactly one entry ID — you just need to know where to find it.
+
+### In the Action UI — no lookup needed
+
+When you use the action through the Home Assistant interface (Developer Tools → Actions, or the Action picker inside the automation / script editor), the `entry_id` field renders as a **dropdown list** showing all your configured Tibber Prices instances. Just select your home from the drop-down and Home Assistant fills in the correct ID automatically. You never have to deal with the raw ID string.
+
+### In YAML — copy from the integration menu
+
+When you write YAML directly (automations, scripts, Lovelace dashboard cards), you need the actual ID string. The quickest way to get it:
+
+1. Go to **Settings → Devices & Services**
+2. Find the **Tibber Prices** integration card
+3. Click the **⋮** (three-dot) menu on the card
+4. Choose **"Copy Config Entry ID"**
+5. Paste the value wherever you see `YOUR_ENTRY_ID` in the YAML examples
+
+The ID looks like a long alphanumeric string, for example `01JKPC7AB3EF4GH5IJ6KL7MN8P`.

+If you have configured more than one Tibber home, each home has its own entry ID. Repeat the steps above for each integration card to get the individual IDs.

All actions (`get_chartdata`, `get_apexcharts_yaml`, etc.) require this value as the `entry_id` parameter so that Home Assistant knows which home to query.
