[text-auditor] Batch fix untracked user-facing typo/grammar families in docs and field descriptions

## Text Improvements

The following user-facing text issues are concrete, low-effort fixes and are not covered by current open `[text-auditor]` issues.

### 1. Repeated punctuation/contraction errors in `rsa.network.alias_host` descriptions (16 occurrences)

**Why:** Clear grammar/punctuation errors in user-facing field descriptions and generated package docs.

**Current text:**
`This key should be used when the source or destination context of a hostname is not clear.Also it captures the Device Hostname. Any Hostname that isnt ad.computer.`

**Suggested fix:**
`This key should be used when the source or destination context of a hostname is not clear. Also it captures the Device Hostname. Any Hostname that isn't ad.computer.`

**Search patterns used for completeness:** `clear\.Also`, `isnt ad\.computer`

**Occurrences:**
- `packages/bluecoat/data_stream/director/fields/fields.yml` (line 1183)
- `packages/bluecoat/docs/README.md` (line 678)
- `packages/cylance/data_stream/protect/fields/fields.yml` (line 1183)
- `packages/cylance/docs/README.md` (line 595)
- `packages/fortinet_forticlient/data_stream/log/fields/fields.yml` (line 1183)
- `packages/fortinet_forticlient/docs/README.md` (line 835)

- `packages/juniper_junos/docs/README.md` (line 781)
- `packages/juniper_netscreen/data_stream/log/fields/fields.yml` (line 1183)
- `packages/juniper_netscreen/docs/README.md` (line 768)
- `packages/netscout/data_stream/sightline/fields/fields.yml` (line 1183)

- `packages/tomcat/data_stream/log/fields/fields.yml` (line 1183)
- `packages/tomcat/docs/README.md` (line 603)

### 2. Runtime error typo in import-beats variable compatibility check

**File:** `dev/import-beats/variables_compact.go` (line 28)

**Current text:** `checking compactibility failed`

**Suggested fix:** `checking compatibility failed`

**Why:** Clear spelling typo in user-facing runtime error output.

### 3. Additional clear docs typos in `docs/extend` contributor text

1. **File:** `docs/extend/add-mapping.md` (line 97)
**Current text:** `- name: cloud.acount.id`
**Suggested fix:** `- name: cloud.account.id`

2. **File:** `docs/extend/developer-workflow-import-beat.md` (line 37)
**Current text:** `1. Elasticseach instance:`
**Suggested fix:** `1. Elasticsearch instance:`

3. **File:** `docs/extend/general-guidelines.md` (line 88)
**Current text:** `When applicable an integrataion package should provide...`
**Suggested fix:** `When applicable an integration package should provide...`

## Suggested Actions

- [ ] Replace the `clear.Also`/`isnt` sentence in all 16 listed files.
- [ ] Fix `compactibility` in `dev/import-beats/variables_compact.go`.
- [ ] Fix the three listed `docs/extend` typos (`acount`, `Elasticseach`, `integrataion`).
