feat: add AvalAI channel type

[m4tinbeigi-official]

Summary

Adds AvalAI as a supported channel — an OpenAI-compatible AI gateway (https://api.avalai.ir) fronting OpenAI, Anthropic, Google, DeepSeek and other vendor models behind one API key.

Since AvalAI is fully OpenAI-compatible, this reuses the shared OpenAI relay adaptor (same approach as LingYiWanWu/Xinference/OpenRouter) rather than a bespoke adaptor:

• constant/channel.go — ChannelTypeAvalAI = 61, default base URL https://api.avalai.ir, display name "AvalAI"
• constant/api_type.go / common/api_type.go — APITypeAvalAI mapping
• relay/channel/avalai/constants.go — ModelList/ChannelName
• relay/channel/openai/adaptor.go — switch cases for AvalAI
• relay/relay_adaptor.go — routes APITypeAvalAI to the OpenAI adaptor
• relay/common/relay_info.go — added to streamSupportedChannels
• web/src/features/channels/constants.ts + lib/channel-utils.ts — frontend dropdown entry + icon

Known gaps — please advise

• go build ./... couldn't complete in the prep sandbox — all failures were network/module-proxy egress errors on unrelated pre-existing dependencies (clickhouse-go, expr-lang, modernc sqlite, etc.), not on any touched file. gofmt -l on all touched packages reported clean. Please let CI confirm a full build.
• Frontend build wasn't run locally.

Test plan

• CI / go build ./... passes
• Manual check: AvalAI appears in the channel type dropdown, test connection succeeds against https://api.avalai.ir

Summary by CodeRabbit

• New Features

Walkthrough

AvalAI is added as channel type 61. Backend mappings route it through the OpenAI adaptor, with model metadata and stream support. The frontend adds its label, ordering, model-fetch capability, and OpenAI icon.

Changes

AvalAI channel integration

Layer / File(s)	Summary
Channel and API contracts common/api_type.go, constant/api_type.go, constant/channel.go, relay/channel/avalai/constants.go	Defines AvalAI identifiers, endpoint metadata, display name, supported models, and API-type mapping.
Relay and adaptor integration relay/relay_adaptor.go, relay/channel/openai/adaptor.go, relay/common/relay_info.go	Routes AvalAI through the OpenAI adaptor and adds model-list, channel-name, and stream-option handling.
Frontend channel registration web/src/features/channels/constants.ts, web/src/features/channels/lib/channel-utils.ts	Adds AvalAI to channel display order, model fetching, and icon mappings.

Poem

A rabbit hops where AvalAI flows,
Through OpenAI paths, the relay goes.
Models appear in a tidy line,
The frontend icons neatly shine.
Channel sixty-one joins the run—
“Sniff!” says the rabbit. “Integration done!”

Translate the AvalAI channel label through i18n.

CHANNEL_TYPE_OPTIONS passes CHANNEL_TYPES labels directly to the UI. The new "AvalAI" value is therefore user-facing raw text. Store a translation key and translate it in the rendering component with t().

As per coding guidelines, frontend user-facing text must use i18n and React components must render it through t().
