<issue_description>We are currently utilizing the Cost Summary prebuilt Power BI template available from the FinOps Toolkit (https://microsoft.github.io/finops-toolkit/power-bi).

While the dataset refreshes successfully in Power BI Desktop, we encounter the following error when attempting to refresh it in the Power BI Service:

Data source error: The 'CapacityReservationId' column does not exist in the rowset.

We kindly request your support in resolving this issue and addressing the inconsistency observed.

Added Power Query logic to generate CapacityReservationId and CapacityReservationStatus columns
Updated Power BI table schema to include the new columns
Documented changes in the changelog

+
+	column CapacityReservationStatus
+		dataType: string
+		lineageTag: 8b4f5c2d-7g9f-5e0b-c6d2-4f3e5b8a9c0e


The lineageTag value contains an invalid hexadecimal character 'g' in the GUID. LineageTags should be valid UUIDs containing only hexadecimal characters (0-9, a-f). The 'g' in '7g9f' should be replaced with a valid hex character (e.g., '7a9f' or '709f').

Suggested change

    BillingPeriodStart         = _swapCol(BillingPeriodEnd,                  "tmp_BillingPeriodStart", "BillingPeriodStart",        each if _isBlank([tmp_BillingPeriodStart]) then Date.StartOfMonth([ChargePeriodStart]) else [tmp_BillingPeriodStart], type date),
-    ChargeCategory             = Table.AddColumn(BillingPeriodStart,         "ChargeCategory",     each if _isBlank([tmp_ChargeType]) then "Usage" else if [tmp_ChargeType] = "Usage" or [tmp_ChargeType] = "Purchase" or [tmp_ChargeType] = "Tax" then [tmp_ChargeType] else if Text.StartsWith([tmp_ChargeType], "Unused") then "Usage" else if [tmp_ChargeType] = "Refund" then "Purchase" else "Adjustment"),
+    CapacityReservationId      = Table.AddColumn(BillingPeriodStart,         "CapacityReservationId",  each if _isNotBlank([x_CapacityCommitmentId]) then [x_CapacityCommitmentId] else null),
+    CapacityReservationStatus  = Table.AddColumn(CapacityReservationId,      "CapacityReservationStatus", each if _isBlank([CapacityReservationId]) then null else if _isNotBlank([x_ResourceType]) and Text.Lower([x_ResourceType]) = "microsoft.compute/capacityreservationgroups/capacityreservations" then "Unused" else "Used"),


The column reference [x_ResourceType] is incorrect. According to the column name mapping at line 66, the source column ResourceType is mapped to ResourceType (not x_ResourceType). This will cause an error when the Power Query tries to evaluate this expression because the column x_ResourceType doesn't exist in the table.

The correct column name should be [ResourceType] instead of [x_ResourceType].

+- **Fixed**
+  - Fixed tag expansion in Power BI reports when tag names contain special characters like colons.


The tag expansion fix appears twice in the changelog:

Line 53 under "Implementing FinOps guide v13" section

Line 95 under "Power BI reports v13" section

Since this is a Power BI-specific fix (based on the context), it should only appear once in the Power BI reports section (line 95), not in the Implementing FinOps guide section. The entry at line 53 should be removed to avoid duplication.

Suggested change

- **Fixed**

- Fixed tag expansion in Power BI reports when tag names contain special characters like colons.

 - **Added**
  - Added export requirements sections to all Power BI report documentation pages to clarify which Cost Management exports are needed for each report.
  - Added Azure Resource Graph as an explicit requirement for governance and workload optimization reports.
+  - Added `CapacityReservationId` and `CapacityReservationStatus` columns in storage-based Power BI reports ([#1839](https://github.com/microsoft/finops-toolkit/issues/1839)).


The issue number in the changelog entry appears to be incorrect. The PR description indicates this fixes issue #1836, but the changelog entry at line 93 references issue #1839. Please verify the correct issue number and update accordingly.

Suggested change

- Added `CapacityReservationId` and `CapacityReservationStatus` columns in storage-based Power BI reports ([#1839](https://github.com/microsoft/finops-toolkit/issues/1839)).

- Added `CapacityReservationId` and `CapacityReservationStatus` columns in storage-based Power BI reports ([#1836](https://github.com/microsoft/finops-toolkit/issues/1836)).
